AIBU to not invite my 20 year old son on a trip with his siblings?

Long one, sorry.

Back in March I found out my husband was having an affair with a much younger colleague. 26 years together. I was devastated, still am honestly. We have four kids my eldest is a son, 20, then a son, 19, then a daughter, 17, and my youngest, a daughter, 15. I moved out with the younger three. My eldest son chose to stay with his dad.

I never wanted my kids to pick sides. But I won't lie, it stung. I expected a bit of loyalty, not because he owes me anything as his mother, but because his dad cheated on me and lied to my face for who knows how long. My eldest told me I was "breaking up the family" by leaving. That one really got me.

My other son and both daughters are angry at their dad too, but they came with me and we've been doing okay. Therapy, lots of time together, dinners, days out. Financially we're fine, both high earners, so at least that's not a factor.
My eldest tried reaching out a few times and I'll admit I went quiet on him for a bit. I wasn't ignoring him out of hate, I was just raw.

Then my younger daughter graduated last month and she chose not to invite her eldest brother, she invited their dad instead. He was hurt, said something angry to her, it turned into a whole sibling blowup, his brother and sister ganged up on him. It's been tense since.

He's told me he doesn't think he'll ever be okay if I date or remarry one day. Says he wants nothing to do with a "blended family." I'm not seeing anyone, not looking to either, but that's clearly already a fault line with him.

Last week I took my younger son and two daughters away for the summer, posted a few photos. He saw them and texted "you could have invited me mama, but it's okay, I'm not your son anymore because your actions are making sure of that. I feel like I have no family and everyone hates me, I'm the outsider."

That gutted me. He's still my son and I love him. But he's also an adult who chose to stay with the parent who broke this family, and I didn't think to include him this time given where things stand with his sisters.

So, AIBU?

Yes, and I do not blame them.

Be the devoted, upright mother: tend to the children, keep the household running, cook, clean, work, meet every expectation placed upon you — only to be met with your children’s resentment when your partner ultimately chooses to betray you.

Oh, joy!

Did you ignore the fact that her son tried to reach out to her and she ignored him. He decided to stay with his dad, he didn't do anything to his mum except chose not to live with her. It was the OP who decided to punish him by ignoring him, despite claiming she didn't want her kids to take sides. Clearly meaning I didn't want them to take sides as long as they took my side.

Don't punish him for loving his dad he didn't hurt his son he hurt you !
And he obviously knew his dad was gunna be left !
As a mother don't play a victim in front of your son !
That's making him pick a side !
You should not have gone cold on him regardless his dad caused these actions not your son !
Sorry I'm blunt but your son is innocent in all this

@Girlwithavibe

OP is innocent too

Sorry OP, but I think you have got this completely wrong. You have chose to frame DS as the villain by staying with his father. His family was falling apart (I expect there were rows and recriminations) and he has chosen to stay in his ‘safe place’. Was it near friends, girlfriend/boyfriend, college, part time job? He is allowed to choose the familiar in a time of turmoil.

But instead of accepting that, you have blamed him, ignored him, encouraged division with his siblings and thrown a family holiday without him in his face. Listen to him - he feels an outsider, he has no family. You did that.

The comment about you moving on was stupid and I bet there’s more context. But it is also a wounded young man who is emotionally immature and is clearly anxious about being sidelined yet further. Again, listen to why he might have said that.

You need to fix this. He’s not responsible for your pain but you are for some of his. Reach out. Include the siblings. Be his mother.

100% agree.

BlueFahrenheit · 12/08/2026 11:03

OP was understandably wounded by his deeply unpleasant remarks. I would have stepped back and allowed him the opportunity to reflect upon the absurdity he had so carelessly allowed to pass his lips.

I would never allow my DC to ever speak to me in this manner without consequence.

Consequences go both ways...

pontipinemum · 12/08/2026 11:24

'My eldest tried reaching out a few times and I'll admit I went quiet on him for a bit. I wasn't ignoring him out of hate, I was just raw.'

This part - this is the part that struck me. Regardless of why you ignored him, he felt ignored by his mother during a very difficult time. Difficult for all of you.

BlueFahrenheit · 12/08/2026 11:23

Rosecoffeecup · 12/08/2026 11:19

YABVVVVVU. You are the mature adult here, he's a naive 20 year old. You have gone quiet on him as punishment and that is unfair.

Is he naive?

He knows what his father did, yet feels it is appropriate to punish his mother? Her other kids know better - the younger ones, at that.

HowardsWahey · 12/08/2026 11:23

I never wanted my kids to pick sides.

"I just ignored his attempts at contact because he chose to stay with his father, then didn't invite him on holiday because of an argument with his sister."

But no - nobody's taking sides 🤔

@Rosecoffeecup

OP can’t force her feelings 🤷‍♀️ Her son hurt her. It’s fine for him to know that.

Clearly! It’s no wonder more and more women are choosing to remain child free…

Strawberrymilkshakez · 12/08/2026 11:20

It sounds like your oldest son is struggling with change. Not wanting to move, not wanting a blended family etc. I think you need to stand up to him more and communicate. This situation isn’t fair on anyone but he is an adult. If you want a relationship with him you need to work on it and start involving him, even in a 1-1 situation. It’s not his fault his dad cheated. I would have probably invited him but it could have been a nightmare if no one got on.

aCatCalledFawkes · 12/08/2026 11:11

Actually there is hurt on both sides. Despite being 20 he’s still the kid and she’s the parent.

A 20-year-old man is a kid?

One has to ask oneself why a grown man would support his father in such circumstances.

Stressedoutmummyof3 · 12/08/2026 11:16

Hoardasurass · 12/08/2026 09:43

You need to sit him down and point out a few home truths to him.
The 1st being that his dad destroyed his family by having an affair and all of the consequences rest solely at his father's door
2nd that he has no right to demand that you stay single forever just because his father couldn't keep his vows or his dick in his pants.
3rd that his own words and behaviours are what is driving a wedge between him and his siblings and you.
And finally that when he is prepared to apologise for his choice of words you are ready to speak and forgive him but you will not accept any claim for the consequences of his or his father's choices and actions.
Then step back and wait he will either grow up and accept that its his father thats to blame or he won't, but if he doesn't I feel very sorry for any women who has a relationship with him because he'll likely cheat on her and then blame her for it too

And what about OPs behaviour? Do you think it's okay to ignore your 20 year old son when he reaches out to you? Do you think it's okay to take all your kids away but exclude one? Shouldn't she apologise for going out of her way to exclude and punish her son just because he chose to stay with dad?

ExtraOnions · 12/08/2026 11:15

OP could have chosen to take the moral high ground when it came to the children, has chosen not to, and has not only fractured her own relationship with her son, but he other children’s relationship with him as well.

BlueFahrenheit · 12/08/2026 11:15

Tessasanderson · 12/08/2026 11:10

How do you know its tasteless poor judgement?

I wont go over it again as PP have outlined reasonable reasons for the son to stay put. None of it nasty, non of it about choosing sides. Just plain old keeping his life balance normal.

He didnt shag this other women, his dad did. Regardless of who he lives with he should not be punished in any way.

Don't you think it's tasteless or shows poor judgment?

His dad chose to penetrate another woman, which ended their marriage.

OP's son chose to live with his father and behave poorly.

They brought it on themselves and must learn the consequences.

LAMPS1 · 12/08/2026 11:14

Your 20 year old had always loved his mum and dad. Equally.

Then you left his dad, (the reasons matter to you …but not here ) and his three siblings chose to go with you.
Nobody can blame your oldest for choosing to stay with his dad…maybe it was just to even things up a bit, and as the oldest he could have felt that as a burden or responsibility to try to do what he saw as the right or diplomatic thing.
You incorrectly took it as a slight/offence against you, when it wasn’t at all.

Your break up and the details of it and your hurt of the fall out and your ‘raw’ feelings, whilst justified for you, were nothing to do with any of your children.

The effects of all that should not have been put on their shoulders in any way.

You should have known that they would simply never ever understand any of it on the same level as you. How could they ? They didn’t have that emotional maturity or that lived experience as a partner.

So yes, OP, subconciously, you did kind of punish your son by going quiet on him. He was already suffering and you let him know how you felt by not responding to him ….as if he had also cheated on you.

It’s black and white for you but it never is for the children….as shown by your daughter inviting her dad to the graduation. You have to go with that, instead of reacting against it. That's your job as a mum. Brush it off and still love them.

Keep your painful divorce right away from your children. Never speak ill of their dad. Try to keep your tears to yourself. You have to dig deep to do all that I know, but if you want lovely relationships down the line with them all, it’s absolutely what you must do …aim to keep your suffering well away from them if you can.

You have a lot of talking to do with your boy. He’s vulnerable even though he’s the oldest. Tread carefully. Apologise for your mistake and make sure he knows you don’t blame him for anything and that you will always, always love him and include him in the future. None of this has been his fault. It was caused between the break up of you and your ex, both of whom he loves equally.
Good luck with everything OP.

Just to add…of course he wouldn't want to have to live with a blended family.
He wasn’t dictating or trying to control, he was expressing a fear. But you couldn’t see it that way as you were too entrenched in suffering your own, all-consuming injustice.

ClairDeLaLune · 12/08/2026 11:13

Your son reached out a number of times and you went quiet on him? YABVU. You’re the proper adult here, you need to fix this or you’ll have no relationship with him going forward.

Yes your husband broke the family up by cheating, but you’re breaking it up further now.

Your poor son was probably upset and hurt and confused and didn’t know how to act at the time. Get in touch with him, apologise, and try to heal this.

hiermetzandvullen · 12/08/2026 11:12

It’s no wonder there are so many misogynistic men marrying and fucking up women’s lives, if they are being pandered to by their mothers, the way posters are suggesting this 20 year old man be kid gloved through his disgusting take on his betrayed mother.

Cherrytree86 · 12/08/2026 11:11

BlueFahrenheit · 12/08/2026 11:09

Evidently, OP’s feelings are of little consequence in this rather unfortunate arrangement.

She is, it seems, expected to remain steadfast, holding the family together while absorbing the aftershocks and indignities delivered by both her son and her ex-husband.

Good gracious.

Yet OP's son feels the need to assimilate comfortably into his father's world while condemning his mother.

Tasteless. Poor judgement.

He is 20, not 12.

How do you know its tasteless poor judgement?

Maybe the father despite his affair, is not emotionally blackmailing his children. Maybe the son can understand why the father had an affair 🤷🏻‍♀️

@Baileyss

that’s so out of order. Why are you so misogynistic??

wheretonow123 · 12/08/2026 11:09

Apologies for going slightly off topic but the "my husband was having an affair with a much younger colleague. 26 years together" bit shocked me tbh.

With the eldest only 20 then the affair must have last for most of the marriage or may even predate the marriage though that would probably have been mentioned in the OP if that had been the case.

BlueFahrenheit · 12/08/2026 11:09

Cherrytree86 · 12/08/2026 11:02

@waterrat

What about OP’s feelings? Do they not count because she is a woman? Because she is a mother? Her son is an adult he should be capable of expressing empathy towards his poor mother.

Evidently, OP’s feelings are of little consequence in this rather unfortunate arrangement.

She is, it seems, expected to remain steadfast, holding the family together while absorbing the aftershocks and indignities delivered by both her son and her ex-husband.

Good gracious.
