15yo son has moved in with Dad & Nana after years of undermining, boundary issues, and constant conflict. I’m heartbroken and questioning everything.

[EmirateReign]

TLDR: Single mum to a 15yo. Dad and Nana have consistently undermined my parenting for years. Son has grown increasingly disrespectful and selfish, refuses basic boundaries, and sees me as the “problem”. A fight over attending a rare family meal (vs football) was the final straw. He’s now chosen to live with Dad and Nana unless I apologise. I’m exhausted, ill, heartbroken, and questioning whether I did the right thing.

There’s a lot to cover in the post so it is going to be so long. If you stick around and read it all, thank you.

Background
• My son is 15.
• His dad and I split when he was under 1.
• We’ve had a roughly 50/50 arrangement, but always built around his dad’s shift pattern, meaning:
• Dad never has him while working only on his days off.
• I’ve always carried the day-to-day responsibility.
• Dad moved back in with his parents after we split.
• Nana (his dads mum) has been heavily involved since day one:
• Doing GP, dentist, school stuff on the days my sons with them.
• Essentially a third parent doing the things Dad should’ve done but didn’t.

I’ve always been grateful for her help, especially when I’ve been seriously ill. But that gratitude has also made it very hard to stand my ground when boundaries were ignored.

Ongoing Issues With Dad & Nana

This has been happening for years, not months.

Undermining from the start
• Dummies, potty training, routines — undone every time he stayed there.
• Nana openly ignores rules and justifies it as “that’s what grandparents do”.
• But this isn’t occasional babysitting. She’s effectively co-parenting.

Food & health
• I tried hard to encourage a balanced diet.
• Dad and Nana accused me of “forcing” food if I added veg or lettuce. I shouldn’t feed him stuff he doesn’t like (he’s a kid of course fruit and veg isn’t gonna be his first choice!)
• Son then repeated their words back to me.

Discipline never sticks
• If I removed phone/Xbox or grounded him:
• Dad would agree… briefly.
• Within days, rules vanished.
• He’d be back on his phone behind my back.

School & money
• Poor school reports — I made plans, Dad said he’d help, then didn’t.
• Son is awful with money.
• We agreed on a card limit. Dad & Nana ignored it within a month.
• I eventually stopped pocket money unless it’s earned.

⸻

Girlfriend & Boundaries
• Girlfriend stays over constantly.
• I had open, responsible conversations about sex and contraception.
• But I was repeatedly woken up hearing them having sex.
• After the fourth time, I put my foot down and said no more sleepovers.
• Grounded him and told Dad & Nana exactly why.

It didn’t last. Nothing ever does.

⸻

My Health & Stress Context (Important)

In the last 18 months:
• 4 months in hospital in 2024.
• Major surgery July 2025, ended up in ITU.
• Long-term illness (including lupus).
• Relationship eith my ex BF (not his Dad) ended while I was still hospitalised.
• Client went insolvent owing me thousands.
• Took on two extra jobs to recover financially.
• Still tried my absolute best to give my son a good Christmas.

I’m not parenting from a place of ease or support. I’m surviving.

⸻

The Argument That Broke Everything

I asked my son if he was free on a certain date because:
• My aunt and extended family (who live far away) were visiting.
• We were booking a family meal.

He said he could “70% come” unless football fixtures came out and there was a home game.

I explained:
• If I say to them he’s coming, he’s coming not oh he can maybe come 70%.
• I can’t mess people around with bookings.

He replied:
• He “doesn’t really know these people”.
• Why miss football for people he doesn’t know. This was said about 4 times by this next point.

I said, out of frustration:

They’re fucking family, not random people.

Things escalated even further. He accused me of being unreasonable and was so condescending and rude saying things like ‘you’ve got the audacity to speak to your son like that, I don’t know any parent that would do that’ this is in relation to me saying ‘they’re fucking family’ after he was repeatedly dismissing me acting like these people were nobodies. I didn’t swear directly at him but I did call him out for being selfish.
I said asking him to miss one football match for rare family time wasn’t unreasonable.

He refused outright and demanded an apology.

⸻

His Perspective (According to Him)
• He never clashes with Dad or Nana, so I must be the problem.
• I “create issues out of nowhere”.
• Other parents would just “leave it”.
• Swearing (context or not) is unacceptable. Even though we both swear in normal chatty conversations so it’s not remotely like we’re a family who doesn’t swear.
• He believes I am the reason the relationship isn’t sustainable.

⸻

My Reality
• We clash because I have boundaries.
• Dad & Nana don’t say no.
• He’s learned that if he waits long enough, rules disappear.
• He is increasingly selfish and dismissive.
• He speaks to me in ways people around me find shocking.
• Yet when things are calm, we’re genuinely close and affectionate and actually have a closer relationship than what he has with Dad. My son can be his true self around me, doing his funny impressions and cracking jokes etc, he would never be like that around Dad.

⸻

The Decision

After talking to friends and family, I realised I couldn’t keep doing this weekly.

For my health and sanity, I suggested:
• He stay with Dad & Nana until exams are over.
• We still see each other Saturdays.
• Remove the constant friction.

He agreed — but said he will only see me on Saturdays if I apologise for the argument.

In the heat of our argument when he demanded the apology I said I’m not apologising for asking you to come to a family meal, we’ll talk about it again when we’re both calm.

Then once the new arrangement was spoken about he demanded an apology again to allow me to see him on Saturdays. I actually ignored that part of the message and just kept calm answering the logistical stuff. When he needed to come for some of his stuff I said I can leave it by the door or he can come in for a chat and that I’d leave it up to him. He said he can only come in if I apologise. Then proceeded to add a list of things he wanted me to bag up for him and actually then asked for his gaming monitor saying ‘it’s mine anyway and at least I’d be getting good use out of it’. He’s asked me before when we’ve been fine to take his monitor to Nanas and I’ve always said no because it’s cable tidied into his desk etc and is a faff to have to undo all that. So he knew full well I wouldn’t have said yes to the monitor but I think he felt like he could push his luck. Inside I was fuming but I just replied calmly and said I’m not sending the monitor but everything else you’ve asked for will be in the bags for you. He then collected them from outside. And my word I was sobbing my heart out. I was heartbroken packing his things and heartbroken leaving them outside.

What life is actually like at his Dad’s (important context)

What hurts the most is that my son has openly said many times that he actually prefers my house because it feels more homely and cared for. At his dad’s, his room is a mess 24/7 because no one ever asks him to clean it, his bedding doesn’t get changed unless he brings clean bedding from my house, washing takes ages to come back from the wash, and there’s rarely food or drinks in the house that he likes. His dad doesn’t think about those things and instead just gives him money to sort himself out or orders takeaways. They don’t really spend quality time together either, my son is usually just in his room when he’s there. He’s also said before that he often goes to Nana’s on nights he’s meant to be with his dad because he prefers it there. So this isn’t about him being happier or better cared for there. It’s about having no boundaries, no expectations, and never being told no, which is obviously appealing to a teenager but devastating as a parent who has actually tried to create a stable, warm, functioning home.

I’m hoping that this whole trial of living with Dad and Nana until you finish school in June will work. I’m hoping that once the initial novelty has worn off of not having rules, being expected to do basic stuff like make your bed etc, once that has worn off I just hope it sinks in for him that actually I’m really not the bad guy.

⸻

Where We Are Now
• He’s living with Dad & Nana.
• Collected belongings contact-free.
• Says he’ll see me Saturdays once I apologise.
• I’m devastated, grieving, exhausted, and terrified this will backfire.
• I’m hoping distance and reality will eventually bring clarity.
• But I’m scared it’ll just reinforce the narrative that I’m the problem.

Why I’m Posting

I don’t want validation that I’m perfect. I know I’m not.

I want to know:
• Was I unreasonable?
• Has anyone else dealt with being the only parent enforcing boundaries?
• Does stepping back ever help?
• How do you protect your health without losing your child?

Because right now, I feel like I’ve lost him — and I don’t know if I did the right thing letting him go live there. I’m not perfect and I know that and have acknowledged that to my son many times. But the things we clash about are always due to him not following some very basic rules. If I was expecting way too much of him or was shouting and screaming at him all the time then I would understand that. But we only ever clash when I say no, and I feel like I have no respect or parental responsibility because everything is always challenged and undermined by the other side.

I just know that I feel beaten down, and honestly a bit depressed in the last few days since the big row. I’m crying a lot, I feel hopeless and powerless like I’m fighting a losing battle. 😢

I agree with you on the vast majority of what you have written. Your son and his awful father and grandmother have significant behavioural problems. But on the football vs family you are 100% in the wrong. He has made a commitment to a team, chances are he would have gone other than this commitment which he flagged early, you could have included this caveat when you said he was coming. This one is on you.

Had it always been just you and him? Or has there / is there a step dad / step siblings?

There’s a real feeling of lack of warmth and fun in your relationship and small wonder if he’s been acting like a knobber - but he is still a child and a bit of a Wally. I think I would give it a couple of days and then ask if he would like to come back home after his exams next week, say you love him and you’d love it if he came back. If you ask him to stay away for the next 6 months you’ve effectively thrown him out and my bet is that if he tires of his dad and Nan he’ll move in with his girlfriend and her dad. He’s too old to play these games with really, he’s going to have options very soon - I’m assuming he’s 16 this year. You can legally leave home at 16. You can join the Army at 16 fgs, and I expect he feels like you’ve dumped him as a son and that’s the narrative that he’s going to cement in himself the longer this goes on.

He’s a teenager who has had very inconsistent parenting and recently had a very very sick mother, he’s got big exams coming up, first relationship - he’s going to be all over the place. Try to be the kind but consistent one and give up some dream that he’ll come crawling back to you because his dad doesn’t make him tidy his room (!). He’ll have his pride and you need to be finding him exit strategies from this situation without anyone having to feel humiliated.

I’m not saying be a doormat once he’s back, not at all, but my feeling is you don’t want to give up living with your son permanently and if you let this run on that will IMO be the result.

Oh honey, @EmirateReign. You need to realize that you’re in an abusive relationship with your son. Yes, he really is emotionally abusive. You’re in the cycle of “Everything is fine as long as I don’t upset him”. Abusers push boundaries, just like he’s doing. He’s manipulating you into apologizing for something you needn’t apologize for in the first place. The family meal was NOT a weird hill to die on, contrary to what other posters are saying. He gets his way every other time and he can’t make one exception to have a meal with his family? That’s unacceptable and selfish.

Everything you’ve been doing, based on the first paragraph of this post, is wrapped up in his wants and desires. That’s what the other poster meant by getting a life of your own. For now, you need to let him go and protect the peace you finally have in your home for the first time in 15 years! Don’t chase after him. Let him in a bit at a time and ensure he knows that your life doesn’t revolve around him. It’s extremely unhealthy.

It may be abusive but I’m not getting that from OP’s posts, he is being an idiot teen and doing basic teen things like moaning about clearing up after himself. What is exacerbating it is the badmouthing which is reinforcing his feeling that he’s been so badly treated. He is really old enough now to understand that different behaviours are needed in different situation and whatever happens at his dad’s his mum sticking to her guns at home will pay off eventually.

Don't apologise - you were at the end of your tether after prolonged ill health and undermining. Let him stay with them for the time being while you enjoy a bit of peace and quiet.
They, and I include your son in this, sound awful.

You'll need to apologise I think. Enjoy the space from him for a while. Try to make your Saturdays enjoyable, don't try to have heavy talks with him during this time.
when he's a little more receptive you need to explain your boundaries are because you love him and want the best for him.

He sounds (like any 15 year old) quite immature.

This is so similar to my life, even the season ticket part! But no one’s fallen out or living anywhere they shouldn’t be. My advice: Go to Amazon and order some books about parenting teenage boys/ teenage boys brains etc. They will massively help you through this as they have me. It’s so hard to let go of them! So painful, I understand. Don’t sweat the small stuff. If you really analyse, did you need him to go because the people really wanted to see him or is it possible you wanted him to go because for 11/12 years he has been your best friend and side kick and you miss him terribly? Im going to bet the latter. Read the books, ring him and tell him how much you love him and explain how weird it is as a mother to go from being someone’s everything to a passing ship in a house and that it’s possible you haven’t dealt with that perfectly. Then tell him that you’ve read the books and you desperately want him home because you will do anything to maintain a good relationship with him, even if it means cutting the apron strings. He’ll appreciate the honesty! Good luck, it’s very hard but I think you can get him back easily. Read the books… they will change a lot of your thoughts and expectations. Also, let go of the past and what happened with Nanna and Dad back then, most single Mums go through that and you’ve got through it now. Good luck, no judgement, understand how hard it all is.

Stay calm, he’ll be back.

Get yourself strong again, stay in contact, remind your child you’re there for them and miss them but work on yourself, you’ve been beaten down and are exhausted. You need a break but obviously not to move too far away emotionally too. To be honest you just sound like two parents that are extremely different and they never learned to compromise. Teenagers are awful. I was. He’ll come out the other side.

My kids are all older, but are still at home. I'd say in all honestly that in a year or two you will be feeling much more ready to kick him out over his bullshit, and that despite you feeling devasted now, what your ex and his mum have won is residency of a surly messy snarky teenager.
I'd tell them all that they are welcome, and tell your son that you respect his decision, and that you hope that he enjoys his time there. That they've all spent years undermining your parenting and mugging you off, and actually now you're really unwell and you need to prioritise yourself, but that you love him with all of your heart, but the drama stops here.
Your son will undoubtedly want to come back at some point, but from living elsewhere, you'll be in a stronger position with boundaries, and you also won't have to deal with your ex anymore.

I think in a few weeks, you'll have got more into a routine and once they all see you aren't fighting them, they lose a lot of their power.

I understand and agree with all your thoughts about reasonable boundaries. The only thing I disagree with was your argument about the lunch and the football. He had said if the football wasn't on and I think that was fair enough. He said he was70% available to go. There are plenty of teens who would have caused an argument about going out with older relatives whether they had other plans or not. I would have said yes to the organisers then; f he couldn't go I would have rang the restaurant and told them there would be one less and let the host know the same. I have rarely been to a big family restaurant meal where somebody couldn't come last minute and it's not a big deal. If you are in a team and you're not reliable you can very quickly be dropped, in which case they lose a healthy activity and end up on the games morals more and isolated in their bedrooms. I can understand you wanting him there but this is a tricky age. It is tempting (I know) when lone parenting to want teens around and expect the same level of companionship you had at a younger age but if he comes back I would pick your battles. it's fine if he's out ages with his footballing mates after matches and after the GCSE age as they mature towards adulthood you can expect him to be spending more time with mates. So much the better if it's with other kids who are doing sport and it's ok to hang out afterwards not feel he has to justify the time away after the activity ends. You sound a good really caring mother. If he comes back I would stick to your boundaries, but pick your battles.As for this Saturday thing, I've no idea what's best ...except that it's important for both of you to resume some pleasant contact ASAP. For me resuming contact would be more important than insisting on being totally 'right' so I would try to meet him half way. ...I'm not sorry I swore but I'm sorry I made an issue over the football. Good luck going forward 💐

I feel for you and understand why you’re upset. You have done your best for him for 15 years and it seems like he’s throwing it back in your face. But I would, for now, take a step back. He’s young and immature and thinks he knows best. He doesn’t, but perhaps needs to work that out for himself. He’s not on the street and you know he is somewhere safe. Let his dad take the reins for a while and enjoy some well-earned rest and some time without strife and aggravation.
If/when he does want to return to you, welcome him, but also put a few more boundaries in place. For me, being woken up by a couple of 15 year olds having sex would only ever happen once, I can tell you. If the girlfriend’s parents want to put up with that level of disrespect, that’s their lookout, I certainly wouldn’t.

Take this time as a break to look after yourself. 15 yo boys are difficult beasts and he may not improve for a while in between hormones and exam pressures.

And there is no amount of words which will make him behave better. All you can do is set the best example you can, show him what good boundaries are and be a safe adult for him from now on.

Just re-read the thread and I can see it was a football match he was attending not one he was playing in my comments about him losing his place are irrelevant but the main points are the same

This

That’s not sending him packing. That’s taking the wind out of his sails if anything. Sending him packing would be dropping him off and saying don’t come back.

Enjoy the break! They can do all the hard work now. The only thing you need to do is keep open the lines of communication, and even then, make sure you're not at your son's beck and call.

Enjoy your clean house, your quiet kitchen, everything staying where you put it and the peace.

I agree that most 15 year olds would vote with their feet in this situation (meal with relative strangers versus footie). Sounds like it was the proverbial straw.

You’ve fought an impossible battle since day one - there’s nothing worse than constantly being undermined as a parent. So this is the result. It’s not your fault and there probably isn’t anything you can do to change it.
it’s hard but let him get on with it. Don’t apologise, you’ve nothing to apologise for. Let him spends time at his dads. Hopefully he will grow up a bit and appreciate what he has with you. Or maybe he will love it there but it seems unlikely.

you do need to play the long game here. I had this for years and it was only once son was an adult that he could see what a total ifiot his father is. Now he only sees him so he can see his half sister.

Football is more fun and important than a family meal especially for a teenager! Your should has rearranged the meal to include him or better let him watch football while you went to meal. I think you do your son an apology.
i would provide a big packet of condoms and suggest he use them every time…

I get no pleasure from being the harbinger of doom but I had a very similar situation with my DS.
The difference in my case was the enablers were my own mother and sibling.

When your DS goes to stay with his GM after an argument with you, does his GM welcome him in and mollycoddle him? Or does she advise him to sort his issues out with you?

In my case, my mother was more than happy to accomodate DS, she never expected him to lift a finger whilst simultaneously undermining my parenting, yet she vehemently denied doing this, but DS would say hugely disrespectful things to me and I couldn't work out where he had heard it from until there was a huge argument and my mother began screaming the same to me, word for word.

I haven't gone into great detail here. I just wanted to say keep the lines of communication open with your DS.
I mistakenly believed that if I gave DS space and time once he chose to live at my mother's, he would begin to see that I wasn't the ogre in the situation.

That mistake cost me my entire relationship with DS, because he was spending a considerable amount of time with the woman who was, unbeknownst to me, parentally alienating him from me, and almost no time with me.

My mother also never expected him to lift a finger, to a ludicrous degree. She treated him like a king. He was never asked to take responsibility for anything.
My mother would pick up all of his dirty clothes, retrieve his dirty plates from his room, drive him wherever he wanted to go at any time of day or night, gave him money whenever he asked for it, bought him alcohol every week when he was just 16, cooked him whatever he wanted and never expected him to say please or thank you.
While I was trying to teach him some life skills, such as how to use a washing machine, or cook, my mother did everything for him, and I mean everything.
She practically worshipped the ground he walked on.

The result?
He had no respect for my mother at all but remained living with her, I don't think he even liked her, but he enjoyed the benefits of living with her where there were no rules or expectations, although imo there is always a price to pay, and the price in DS's case was that my mother became very intrusive in his life, calling his friends and asking where he was, logging into his social media and nosing at his private mail.
She appeared to be obsessed with him and wanted to know every single detail of what was going on in his life.
Despite resenting this, he remained living with my mother because he was told he wasn't wanted at my home. I tried to explain this wasn't true but he had had years of listening to my mother undermining my parenting and being extremely negative about me, most of which was lies that i couldn't prove either way. It was a case of her word against mine and i wasn't aware of the majority of what she was repeatedly saying to him so I couldn't defend or explain myself.

As for our parent/child relationship,

He never came home again.
6 years after leaving my home, he cut me off without explanation.
He refused to answer my messages or calls and when I attempted to visit him at my mother's, if he was there, she would refuse to let me in, leaving me outside sometimes for hours.
If I turned up at hers unexpectedly, he would leap out of the back door and my mother had an arrangement with him where she would only message him after I had left.

Eventually he moved out of my mother's when he bought a property and promptly cut my mother off too (apparently, but I can never be certain this is true).

I have not spoken to DS in 12 years now.
I will probably never get the opportunity to speak to him again.

My mother has lost her whole family except for the sibling who helped her orchestrate the alienation.
I feel no sympathy for her.

Please keep the lines of communication open with your DS.
If it takes an apology from you to save your relationship, apologise.
Don't underestimate the lengths people will go to, to sever your relationship with your DS, if they believe this will strengthen their relationship with him. They already undermine you and say negative things about you. They are not on your side.
Don't give them the ammunition they are seeking, based on your principles of teaching him to pull his weight, especially when he is not under your roof.

I think he might just want an apology for when you swore at him in anger. I completely understand how frustrating this whole situation is, but it’s good to know you’ve raised a son who refuses to be sworn at in anger. This will really help him in future relationships with what he’s willing and not willing to accept.

It also sounds like you’re butting heads because you have very similar personalities. This teenage stage is really hard on lots of parents, he will come to realise your good intentions in a few years time. Apologise specifically for swearing. If he won’t accept this language from his Mum, he won’t accept it from anyone in the future which is what you want.

The text message seems brief enough (adore you is a bit much) don’t write a letter, whatever you write will be thrown back at you for many years. He expects you to crumble, apologise and grovel. You’ve apologised, now move on and don’t offer any more. Live your life, get well and he will mellow. Let him get through his exams and mature a little.

Don't apologise. You are burnt out and need a break. Do you have access and funds for counselling? You need to give everyone space for the sake of your mental health. He is selfish and entitled but that's because dad and grandma have raised him to be. Forget about the silly fight. You need time and space for yourself. Do not apologise.

There’s no way I would let my DS miss a family meal for a bloody football match unless he was actually playing and it was a big important game.

If he spoke to me and treated me how your DS is right now I would be leaving him to it with his amazing dad and nan and letting him learn by living with his choices - he’s not going to listen so he will have to live it out to understand.
