Older son from first marriage causing issues

676 replies

Mummamia87 · 04/08/2026 19:22

I would value people’s opinion please. I've been with my husband for 12 years, married for 5, and we have a little boy who's 3.

Before we got together my husband was in a long marriage from which he has an adult son, now 29. They haven't spoken since we got together . Yes it was through an affair which I know that was wrong but it wasn't just a fling. His marriage was effectively over, he was deeply unhappy, and we’ve ended up building a wonderful life together. I know that's only my perspective but I'm not here to debate the affair itself - it was a long time ago.

The issue is that every time our son reaches a milestone my husband reminisces about when his older son did the same thing. I completely understand why, but because they're estranged, it almost always ends with him looking sad.

Instead of just enjoying our son's moment, it's overshadowed by grief over the son he no longer has a relationship with.
I'm increasingly resentful that our son's milestones seem to become bittersweet instead of joyful. I want to say to my husband that our little boy deserves to have his achievements celebrated without them immediately becoming a reminder of someone who wants nothing to do with him.

Am I being unreasonable for feeling this way? Is this something I should keep to myself, or is there a kind way to raise it with my husband? Or do I simply need to accept that this is what grief over an estranged child looks like?

A few people have quoted me, as I thought they would. Sure, people can harbor resentment. I know of one particular person where this is exactly the case. If the wounded party wish to punish the instigator by eating their heart out for the rest of their life and holding grudges then that’s on them I guess.

like a pp @Winederlust i think?( Sorry if I got that wrong). Mum had an affair when I was 12 also. She eventually married him. I wasn’t his biggest fan but…life I guess. You grow up, you look back with different eyes, you see that things weren’t great and while you love both parents you see that like everyone else, including you, they’re flawed. I don’t know what I would have done without my mum in my life. I would have been poorer for it, so would my children. I would have broken her heart.

Sometimes it's not about harbouring resentment, but more that the parent won't add anything worthwhile to their life that outweighs the negative impact the parent had.

If a parent has an affair and leaves, and is (for instance) caught up in their new life and partner and prioritises them, while the child actively doesn't want to see that parent because they're still hurt and angry... Well, time passes with the parent being absent, and the child becomes accustomed to that absence.

Their life may be worse because of their parent's actions, and they may feel as though their parent never took responsibility or allowed the child to hold them accountable, so they have a low opinion of the parent. They may consider trying to build a relationship with that parent to be a potential stressor, and don't think they'd enrich their life... So they just never bother.

The thing with affairs, OP, since you lack insight into the damage is the abuse, gaslighting and emotional toil, the cheated on partners will have had to endure before discovery. Guess who has a front row seat to that, the children in the family home. Is it any surprise the son is disgusted by his father, and you?

watchingthishtread · 05/08/2026 10:35

Am I being unreasonable for feeling this way?

Yes. Very.

Freeyourmind · 05/08/2026 10:36

Guilt does have impacts for a long time, so it was perhaps inevitable that if you upset your child to the extent that they don't want to talk to you again, that there would be consequences to that going forward.

I've never been impacted by an affair, so I've no personal experience to gather from here, but I was struck by your comment that you think the son is being unreasonable for not allowing an apology. Your husband presumably isn't sorry is he, he did what he wanted to do, followed his heart, knowing what the consequences of that were. So I actually think you are being hard on the son, he doesn't have to accept a hollow apology.

Maybe if you see this through the oldest son's eyes, then you will feel your son isn't actually missing out at all, he has his dad there all the time.

Wheresthebeach · 05/08/2026 10:38

You DH needs to come to terms with the estrangement and be able to enjoy your family. Sit him down and have a discussion about it, harking back to his oldest son's milestones isn't healthy and isn't fair on your son. Some counselling would probably help as it sounds like he's grieving. I had similar, although not the same background, met DH once he was separated but had similar comparisons which I shut down as it wasn't helpful. My view was that the decisions he and his ex made had no bearing on the decision we make for our DD. That's part of being a step/second family I'm afraid.

chocoluv · 05/08/2026 10:42

Surely you knew having a baby with him was going to make him miss his other child even more??

He’s going to want to make sure his second son knows about his half brother and so he’s going to keep talking about him.

He’s going to have much more guilt than someone who got remarried without having an affair and so he’s going to be trying to compensate for it.

Kindly, he probably has started resenting you quite a lot. He may resent his new son a bit but it’s more likely that he’ll be resentful of you, blaming you for taking him away from his son and now having another one.
I have seen it many times before.

Was it his idea to have this baby or yours?

He should have tried to repair the relationship before having a second child but obviously that’s in the past now.

You just need to encourage him to keep reaching out to his son and try and rebuild the relationship.

It may be better reaching out to the ex wife and apologising for his behaviour etc and repairing that relationship first.
The son is obviously going to feel loyalty to his mum and if the mum still hates him, so will the son.

CaptianMunchen · 05/08/2026 10:44

You don't mention what your DH has missed in his son's adult life. If he's sad remembering milestones of his older son, then I can only imagine that he feels deeply sad about the adult milestones he will never see: graduation, marriage, and potential grandchildren he will never meet.

Hopefully he has got it right the second time because he's going to need you to support him through this.

Mangelwurzelfortea · 05/08/2026 10:44

Classic shit dad behaviour - boohooing about the son he didn't care about losing when he decided to marry his mistress. He made a choice and has to live with the consequences. The OP is deluded if she thinks he's going to turn out to be Father of the Year second time around.

shhblackbag · 05/08/2026 10:46

You're in the finding-out phase. Actions have consequences, and now you're forced to deal with them. That's life.

My old boss left a very happy marriage for the woman he had an affair with - he told me this himself. The affair originally started out of boredom rather than any actual unhappiness, and then it somehow seemed to spiral out of control.

He desperately regretted it afterwards as he realised far too that his new wife was younger and more glamorous but lacked the intelligence, kindness and sense of humour that he had loved about his first wife. He also felt desperately sad about having wrecked his children's lives, and having new children with his new wife only reminded him of that. If he could have turned back the clock, then I'm 100% sure that he would have done, but he knew that the damage had been done and so he tried to make the best of the situation that he had created.

We had originally been good friends, but I lost all respect for him when I realised how easily his head had been turned and how lightly he had tossed aside his first wife and children. I told him this quite honestly, and he said that he had lost respect for himself as well. I did feel kind of sorry for him, but equally, you reap what you sow.

I wouldn't mind betting that many men on second marriages realise far too late that they have made a mistake but it's too late by that time for them to do anything about it. I think women tend to think things through more but I could be wrong.

Absolutely, spot on - I am a long-time reader of MN and some stories stick in my mind - like that story where a second wife was bemoaning the fact that her husband was enjoying spending time with his first marriage children and not with the new little guy, how he had been telling her about bath times and playing football with them when they were toddlers and he did not want to do the same with his new child, etc. etc. But a common theme through such posts - previous families, those children they just steal energy from 'our happy little family'. None so blind as those who will not see. Astounding blindness.

If the OP’s husband ended the marriage first and then began a relationship with the OP his oldest son probably would still have fallen out with him anyway.

CountessBinface · 05/08/2026 10:50

The adult son is not 'causing issues'. He has exercised his right to break off contact with someone he no longer likes or respects.

Well he might have. We won’t know. But at least then Op wouldn’t have been a factor in the marriage breakdown

Mummamia87 · 04/08/2026 22:26

I expected some backlash but some people have been quite harsh. I accepted in my post that what we did was wrong but we are 12 years down the line and I refuse to waste my energy on an adult that clearly wants nothing to do with me or his DF. Before you all jump down my throat I understand why that is the case. I also understand he is angry with my DH too but again, if he does not want contact that has to be accepted. No issue with DH being sad about that I just don't want that to impact on our son. As people have said, it is not our son's fault.

My DH has tried to repair the relationship but he point blank refuses to enage. IMO (and I know this wont be welcome) I do think his first son is being unreasonable to point blank ignore him. He has not even given him an opportunity to apologise. He is an adult now and must realise that people make mistakes and no one is perfect.

And no I am not looking over my shoulder. Sometimes people do find the right one second time around, even if that is through an affair. The affair being wrong does not void the connection.

Some great suggestions for therapy and journalling, I will suggest those, thank you.

Edited

"He is an adult now and must realise that people make mistakes and no one is perfect."

The problem is he wasn't an adult when the 'mistakes' were made. So while an adult may be able to get over it, it takes time, effort and willingness. As your DH has reached out there is nothing more he can do that reach out periodically and show he wants a relationship with his first DS.

You have to accept reality, your DS's milestones will be bitter sweet for your DH, he can't change his feelings. All you can ask is that you both treat your shared DS with the level of celebration you want him to remember as he grows up.

Good luck. No one is perfect.

Oh come on. Ending a marriage in a way that promotes dignity on both sides and that doesn't involve lying, sneaking off and leaving one party in the dark is unlikely to sully relations to this depth.
Still sad for all parties but far less room to feel betrayed.

The point is though, with this harsh "vengeful" behaviour, the first wife and son are confirming what they're really like, as the husband doubtless already knew. So he really needs to accept that he's well off out of it.

Same applies of course when wives leave miserable marriages for sunnier relationships, and in Mumsnet they are of course quite rightly encouraged to do so and applauded when they succeed.

It's just a bit odd that so many posters can't see how they apply completely different standards when it's the husband who manages to escape.

What vengeful behaviour is the ex wife or son displaying?
The ex wife has and is doing absolutely nothing to @Mummamia87 her husband or her son.
The older son is also doing absolutely nothing to anyone other than choosing not to have a relationship with his cheating scumbag father who wrecked his homelife when he was going through his exams and went on to play happy families with his equally disgusting affair partner who has zero empathy, shame or remorse for the part she play hin ripping this poor boys life apart.
The fact is op is scared that her husband will treat her and her son the way he treated his 1st family because hes starting to regret being with her and can see the true cost of his actions and soon enough he'll be asking himself if she was worth it and wondering if he could mend fences by ditching his affair partner assuming ofcourse that he isn't asking those questions already

NCForOneNightOnly · 05/08/2026 11:04

Well I suppose at least you know what he’s capable of when he decides your relationship is dead too.

HollyhocksandPeons · 05/08/2026 11:04

SeasideDaisy · 04/08/2026 19:43

Exactly, I have a friend whose young daughter is refusing contact with her dad because he had an affair. My friend has really tried to explain to her daughter that she’s fine now and she loves her for her loyalty but she doesn’t want to see her lose her relationship with her dad. Her daughter is still refusing and has said she has no respect for him and doesn’t want to forgive him. He’s probably sat around feeling sorry for himself to. Like they say the grass isn’t always greener on the other side.

What a decent human being for a daughter your friend has. Not many children understand what loyalty is, give them a new iPhone and hey, presto, can I see daddy? I knew a crafty bastard who got his new wife gift the newest iPhone to his daughter to 'build bridges'. How horrible people are.

OnlyUsername · 05/08/2026 11:05

He picked you but that will always make him a bit sad.

Oh well. Tiny violin.

AgnesX · 05/08/2026 11:09

Yes, say those words to him. Your child deserves better than a father harking back to the past.

I really wish that people would give consideration to the consequences of their actions and how it might impact both them and their wider relationships further down the line.

GeneBelcher · 05/08/2026 11:17

Oh my goodness, you're infuriating!
Stating that the son is being unreasonable to still harbour antipathy towards his father- how dare you.
I would have cut you some slack, you were obviously dazzled by an older man (albeit a cheating, shit one). I do understand how a younger woman can be blinkered plus you didn't have the maturity or life experience to truly grasp that what you were doing- the affair- was an appalling thing to do.
But here you are, 12 years and 2 kids later, and you've learnt nothing, you're as bad as your husband.
I feel dreadfully sorry for your son and hope for his sake- no-one else's- that his father is able to fully engage with his milestones.

When a parent decides to blow up his marriage, he is also blowing up his family. Your DH may not see it that way, but tat is what he's done. In having an illicit affair with you, @Mummamia87 he demonstrated to his son that you are more important to him than his DS.

You participated in that explosion of your husbands's son's family, @Mummamia87 but neither of you seems to want to take responsibility for that. Your DS is your DH's second son. It's what you signed up for.

Your dismissal of your DH's elder son is casual at best, and scarily lacking in empathy at worst. You can't be much older than him, which probably adds to his resistance to seeing his father.

Actions have consequences, OP.

This answer is spot on.

OP and her DH hurt a child so profoundly that they have undoubtedly altered the course of his life. Now she wants the grown-up who was that child to just get over it so she can have the happy life she dreamed of. Meanwhile eldest son, remembering the pain these two inflicted on him, has decided his best chance of happiness lies in keeping far away from them.

LizandDerekGoals · 05/08/2026 11:20

I think the pp about men don't leave happy marriages is not true. I dont think that leaving a marriage was always, or often, the primary focus. Quite often the man leaves the wife AFTER the wife has found out about the affair and the wife ends the marriage. The man wanted an affair because he wanted an affair. Leaving his wife wasnt a factor. Because if he intended to leave an unhappy marriage, that is the action he would have done. Some men have multiple affairs, or long term affairs. They have no intention of leaving their marriages. They only leave when their wife finds out and begging doesn't change her mind.

Id be interested to know if op’s husband left his marriage before or after his wife found out and also what prompted him to leave the marriage.

but ultimately, op’s husband chose his mistress over his son. Of course his son does not want anything to so with him. Id also be curious to know what over the years the op’s husband has done to try to improve his relationship with his son…

Mangelwurzelfortea · 05/08/2026 11:22

Imagine being the sort of person who chooses their mistress over their son.

And then being sad because that son doesn't want anything more to do with them.
