AIBU to question what my fiancé expects of me as a stepmum?

Hi,

i’m engaged to a man who has a child (aged 7). I’ve be with my fiancé for 4 years, and in his child’s life for 3 years (we waited to introduce me to his child as they’d had a lot of disruption in their short lives).

this is my first time in a relationship with someone who has a child. From the beginning I really tried my best to be kind, loving and caring towards my stepchild. I feel like I am a good stepparent and that stepchild likes me, maybe even loves me. I love my stepchild, I love it when they’re here, love chatting and playing with them (as long as it’s not with figures haha), love our family days out.

I don’t want to assume a mother role as my friend has a stepmum who did this and she resented her (still does) that she tried to be that to her. There’s a few things I don’t do, bath times and school stuff. I feel that’s overstepping the mark

fiance has recently said I need to be “doing more” and that “you’re a parent now, so you need to think of these things, you need to do XYZ”. He’s very critical if i have an appointment or seeing a friend on the days stepchild is at home with us.

he also said that I should love stepchild as my own. I don’t know what this means - I’ve never had a child, I don’t understand what that love is. And then I got thinking, I don’t “miss” stepchild when they’re not here, I don’t feel an urge to rush home to be with them. I’d do anything for them, but I don’t feel intense love.

fiance has said that I am very privileged to be a stepmum, and that I should be over the moon. He also said that he doesn’t me separately to being stepmum, for example, he said im a family member, and so it doesn’t matter if im his partner or stepmum. he said when stepchild is here, we can still function like a couple but include them in dates, eg. Date night with us all.

Im really confused. Should I be doing more? Am I a terrible stepparent?

I am not surprised by your update. So now you have 2 occassions where you clearly saw he doesn’t care about your wellbeing (being ill for weeks some time prior and now migrane this weekend). Both produced the same reaction from him- zero care, annoyance and anger. This now not an accident or one-off, this is a pattern.

Like others said, there is coercive control here. He is not the nice man he attempted to portray himself as. It’s ok. Luckily, he has trully revealed himself before you got married, at this point you can walk away and recover from this and look back on the whole experience as a nightmare you managed to wake up from. And a massive upgrade on your red flags radar which will come in handy in life.

You don’t mention what is your housing situation, i hope you are not too intertwined. Even if you are, there can be solution found for that. Short term pain for long lerm gain.

Glad your mom is supportive, it doesn’t sound like she was hugely surprised.

Re engagement and wedding- who cares what who might think what, soon all will be forgotten as people have their own lives to attend to. Cancel it, tell a few close friends why, all will be fine.

Please do take all valuable items from your house asap, i also get the impression that your partner is capable of greater abuse, he has shown you he doesn’t care much about your wellbeing. Hope for the best but prepare for worst, then you won’t be caught off guard.

I wish you best, turbulent times ahead but it will all settle eventually and you will be able to breathe with ease.

Good luck OP. He dipped his wick and pro created, not your responsibility.
your mr right will come without baggage and you can start your own family. Leave him to deal with his responsibilities.

scoobysnaxx · 11/05/2026 09:04

Yeah you just need to leave period. Absolutely sorry excuse for a father.

Just thought I’d update.

He’s escalated over the weekend and shown me in no uncertain terms that I’m an on duty babysitter. I had a migraine yesterday and had a nap around 1pm. He slept on the couch last night and said he’s “sick of all the rest I get whilst he has to get on with it”.

Today I was meant to visit my elderly mum. He said “oh so you’re “sick” yesterday but you have enough energy to spend time with your mother today and leave me and dsd again, having spent no time with us yesterday?”

for context, I spent all day with them yesterday, bar the 1 hour nap.

i didn’t end up going to my mums because i just knew the atmosphere I’d come back to. Cue him saying “why’ve you cancelled going to your mums?” All shocked.

I have told my mum everything (there’s more than just what’s on this thread, but I don’t have the energy to type it). I am going to work as normal tomorrow and then driving straight to hers where I will stay for however long I need/want. She told me not to let him know I’m going.

My ex husband had a son. He turned me into his son’s nanny without myself realising. When I left he stopped shared care. The little boys mother soon realised who was caring for him and he barely saw him. His child will be okay. This man doesn’t need shared care at all since he clearly can’t cope and needs his partner to actually parent his child.

ThisJadeBear · 11/05/2026 08:59

Also to add, if he’s interfering with precious time with your lovely mum, that’s enough to stay away.
It was terrible what he’s just done to you.
I hope some time away will give you the courage to leave for good.

Cycleaway · 11/05/2026 08:12

Well done OP. You were doing everything right in respecting you weren’t a parent, and the fact this angered your partner is extremely telling.

well done for speaking to your mum and taking action before you felt too enmeshed to do anything. Sending strength and the Very best of wishes for you moving forwards 💐

Laurmolonlabe · 11/05/2026 07:46

The red flag is your fiance , not the stepchild- no one is thrilled to have a step child, much as you might love children in a perfect world a fiance without a child would be much preferred. Why does he think you should be thrilled? it sounds as if he wants you primarily to take the child ff his hands. You have been as supportive as you can be , but still your fiance wants you to do more?
I would run a mile.

cooldarkroom · 11/05/2026 07:21

Bravo, Excellent that you have decided to remove yourself. Remember the script, he will promise it was a mistake, that you fill their lives, that yes he is lost without your help, because he Lurves you so, he will promise, holidays. Bring flowers… Dont fall for it, He lies.
Then when you dont return, he will get nasty, do his maximum to damage your reputation, he will lie that it was him who ended it, lie to the child, his mother. If you have any money tied up together he will use this to punish you.
So be ready

jeaux90 · 11/05/2026 06:55

Well done OP don’t look back. If you have someone to go with you to get your stuff that will keep you safe. I’m so glad you have family support. He is awful.

asdbaybeeee · 11/05/2026 06:21

Good for you op. You deserve better Flowers

CheeseAndTomatoSandwichWithMayo · 11/05/2026 02:17

End the engagement. End the relationship. Do you need to sell the house to get your financial share? Can you move most of your stuff to your Mums whilst he's at work?

Thank god you didn't marry him. He's awful

AcrossthePond55 · 11/05/2026 01:10

@Theworldonfire

Oh I'm so glad!

I echo above PP. Take your 'electronics', and any important papers you can stuff in your largest handbag. You can always say your laptop is 'acting up' and you're taking it to a repair place near work. Or someone in your IT department has volunteered to take a look at it.

I'm hoping that this is the first step to ending it with him because he is not going to change and he's made it clear you're nothing to him but a nanny and 'housekeeper'. You deserve better.

Remember, you'll never meet Mr Right when you're tangled up with Mr Wrong.

99bottlesofkombucha · 11/05/2026 00:38

Thank goodness you’ve seen what he’s really like! He doesn’t love you op, there’s no genuine caring for you. I was horrified by the ‘I was sick for 4 weeks’ story.

Studyunder · 10/05/2026 23:55

Don’t ever doubt yourself. You are the most important part of your life! Take anything that’s dear to you/important. Sending you strength

DrinkFeckArseBrick · 10/05/2026 23:40

Good luck OP, I know it's not easy but I'm sure you're doing the right thing x

Your mum sounds ace. Glad to know you are being supported. He is an arse and I feel sorry for his poor kid. I don’t know much about what causes migraines but not having the stress of living him certainly won’t do you any harm.

I'm so glad you talked to your mum and are going there to stay. He's really shown his true colours. What a hideous specimen. Thanks for the update and wishing you all the best 💐

PS what a fkn shit parent he is!!

This

GingerdeadMan · 10/05/2026 23:06

So glad you are leaving him, he's treated you like shit and it would only get worse.

Reminds me of my ex husband. I left him and never looked back, and the same will be true for you xxx

Chickadeeinme · 10/05/2026 22:12

Make sure you take your passport and any bank stuff of yours with you. Most other things are easily replaceable.

Lmnop22 · 10/05/2026 22:01

I’m so glad you’re leaving. Even if you were DSD’s parent, imagine getting stick for needing a nap due to a migraine and visiting your mum at the weekend…! And you’re not even the parent and you’re getting more heat and pressure to parent than her own mother would get

shhblackbag · 10/05/2026 21:41

TeaCupTinsel · 10/05/2026 19:36

Yes...this! Pretend you're going to work but call in work that you need a day off urgently.

Then clear everything out to your Mums! He won't expect it and you'll be safe.

Agree with this. Good luck, OP. Wishing you well.

AnneLovesGilbert · 10/05/2026 21:25

Sounds like your mum has the measure of him and really well done for being honest with her, I know how hard it is to admit your relationship isn’t what you’d want it to be, it’s a massive step and so is going to hers from work.

When I left my ex I was too scared to tell him my plan so I said I was going to stay with my sister for a few days to help her with something and never went back. I called him a week later to say I was filing for divorce, he went mental and insisted we meet where he screamed and shouted at me and threatened me and then he stormed off. Like that was going to change my mind 😂🤦‍♀️ By then I’d got some space in my head from not having been in the same house with him and just powered on sorting practicalities. You’re being very brave and you’ve got us here to support you as and when you need it.

ChavsAreReal · 10/05/2026 21:23

Take your passport/laptop/photo album with you tomorrow. Just in case...

You sound brave. He sounds like a lazy useless good for nothing. Good luck tomorrow.

BleedinglyObvious · 10/05/2026 21:21

Gather anything sentimental, paperwork, jewellery, passport etc., and bring them with you.
He is quite capable of destroying stuff or losing your stuff out of spite.
Take anything of real value.
Do not tell him anything.
This.
