Final update: Aita for exposing my wife’s cheating and not wanting to do anything with a child that isn’t mine

Betrayal cut deep into his soul when he discovered the child he had raised with love wasn’t his by blood. The walls of his world crumbled as he grappled with the truth, torn between the desire to escape the pain and the fierce determination to protect the innocent boy who called him Dad. Every visit, every moment spent with his son became a testament to a love that defied biology and a silent promise to shield him from the storm.

But the weight of forgiveness and the pull of family ties grew heavier with each passing day. Surrounded by pleas to reconcile and hold the fractured pieces together, he stood at the crossroads of heartache and hope. His wife’s regret echoed in the room, yet his resolve remained clear: his love was for the child, not the betrayal that fractured their past. In this tangled web of hurt and healing, he faced the hardest choice of all—whether to rebuild a family built on fragile trust or to protect his own wounded heart.

Final update: Aita for exposing my wife's cheating and not wanting to do anything with a child that isn't mine

It has been a difficult few months. I considered running away from everything, even abandoning my son, although I know he is not biologically mine. However, I did not want him to suffer.

Since then, I have visited him frequently. I moved out but continued visiting him, while my wife tried hard to make me stay. Her sister also caused significant trouble, but I tolerated it all for my son.

This Christmas, after I celebrated with my son, my wife, her sister, and their family sat me down for a ‘talk.’ They wanted me to reconcile and not give up on my family.

My wife admitted she made a mistake years ago, said she could not change it, and wanted to stay with me. I told her that was impossible; I was doing everything for our son, not for her or anyone else.

They all countered that we had been living peacefully, that I had a loving family, and that I love my son despite him not being mine. They insisted I should not break the family, take my time, forgive my wife, and live as we did before, emphasizing that the past is past and she has been faithful since, promising to give me my own biological child.

After hearing all of that, I realized there was nothing else I could do. I told them that what my wife did was a betrayal—not just cheating, but making me raise another man’s son. I tried my best not to complicate things and did everything for my son.

I informed them I was leaving and filing for divorce, giving up on my son, and then I left. They tried to stop me and are still sending texts and calling, but I am ignoring them.

I have decided to file and have spoken to a lawyer. My position is that I either get full custody of him or I give up on him. I am not overly concerned about child support, but it is painful.

I did my best to give my son a good life even though he isn’t mine and wanted him to have both parents, but she is making it difficult. If he ever needs my help or wants to reconnect, I will help him, though I know custody will most likely go to his mother.

Here’s how people reacted:

NTA. Your wife betrayed your trust in a huge way, and it’s understandable that you’d feel hurt and confused. You invested years of your life raising a child you thought was yours, only to find out that wasn’t the case. Even though you’ve grown attached to him, the fact that your wife hid this from you and has now pushed you to reconcile and stay with her because she “made a mistake” is a lot to process.

You did what you could for your son, and you clearly care about him, but that doesn’t erase the betrayal you’ve been dealing with. You can’t just forget that, and no amount of her or her family’s pressure should make you feel obligated to stay in a relationship where your feelings of betrayal are dismissed. You’re right to make your decision, whether that’s to pursue full custody or walk away from the situation entirely.

Your wife and her family might try to guilt-trip you, but at the end of the day, you have to look out for your own well-being. If your son reaches out later, you’ve made it clear you’ll help him, but for now, it sounds like the best choice for you is to move on. You can’t force yourself into a relationship where trust has been broken beyond repair.

She let someone else creampie her after making a deliberate decision to go after someone behind your back, made you raise the kid, and tried to get her entire family to gaslight you into a decision where there would be no adverse consequences for her. The fact that you still tried to be there for the kid shows what kind of person you are and all of her actions and disgusting lack of accountability or compassion for the possible consequences of her child speaks volumes on the kind of person she is.
Do what you can for the kid if you love him, but don’t do anything that would force you into a position favorable to her, actions have consequences, not just for the people who choose them but for the people around them, and she’s going to learn that the hard way. NTA
DarbyTOgill123

Of course, you have to leave, and you have to fight against her getting one red cent from you. Her insane family can foot the bill. It is sad about the boy.

She was prepared to betray you with another man, then continue to protect that betrayal for decades to come while you provide for her and another man’s child. Her family defends that@!! WTF is wrong with these people. Get a good lawyer with many personal connections within the legal community where you are…you may do alright. This kind of shit is criminal and the whores have to start being held accountable and feeling it in their pocket book. Unreal. 😡

StillMostlyConfused

NTA But you should be concerned about child support. Right now, it’s emotional so you don’t think that you should be. You need to prepare for your future which is always unknown. If something were to ever happen and you become financially unstable, child support can destroy you.

Laws have changed about when you find out that a child isn’t yours and what you should do. So I’m not as caught up as I should be to offer advice.

Regardless of whether you decide to continue with divorce or not, get the paternity and child support part figured out now with your lawyer!

Still NTA

No woman (especially those on Reddit) is ever going to understand what you are going through (and frankly most of them don’t give a shit).

You have no obligation to your cheating wife or her son unless you CHOOSE otherwise.

Women can never be victims of paternity fraud but have no problem voicing their opinions in situations like this.

Those same women tell men to shut up when it comes to decisions about abortion, so they can shut the hell up about this situation.

Good luck however this plays out for you.

Savings_Ad3556

There is no such thing as “I made a mistake” when it comes to infidelity. This is a conscious poorly made decision. Bumping into someone is a mistake. Misplacing your car keys is careless mistake.

Cheating and creating a whole human with another person is INTENTIONAL.

If she can’t acknowledge that then there is no point in trying to have any sort of relationship with her.

I am sorry for the child, HOWEVER, she is only going to use your love for this child to manipulate you. You should not allow that.

Starlighttikigirl

Yes, you are the AH. as it relates to the child Parenting isn’t always biological and you are taking your anger towards your wife out on a little kid who only knows you as their dad. You complain about him being another man’s son but you want full custody or you are cutting ties? Yeah, zero respect for you and your stance as it relates to the child. The wife, NTA – she made a choice and you shouldn’t stay for that. But to cut out the child from your life because of her transgressions, yeah, 100% YAH.
blackcatchihuahua

Good for you. You tried to set boundaries, and they were stepped all over.

I understand that it’s hard a D it’s painful as hell. But you need to do what’s right for you.

Idk how your state works, but maybe ask if you can still do 50/50 with supervised trade-offs when it’s your time with your son instead of all or nothing.

Again, your choice. I’m just trying to offer an option that might not hurt as much.

Necessary_Sir_5079

They went straight to using that child as a weapon to manipulate you the minute you tried to stay in his life. That’s so sad and don’t blame you for setting those type of boundaries up. They way overplayed their hand instead of accepting the reality of the situation. Sorry it’s turned out like this but just listen to your lawyer and do what you gotta do. Good luck op. 
TaiwanBandit

You are an honorable man that was baby trapped by an awful woman. That whole family is toxic for trying to convince you to stay.

Did she ever admit who the real father is?

Divorce that whole group, take time to heal, then when ready look for a loving, caring, faithful partner.

Thanks for the update OP. Take care of you. updateme

MobileRub1606

NTA. I hope you can stay in your sons life. I think your ex and her family are TA. Trying to guilt trip you into forgiving her. Some people can forgive, and some people can’t. You have to respect how the person chooses to deal with your betrayal. Your choice is to leave. Good luck!
Competitive_Sleep_21

YTA. All or nothing means you likely are giving up on your son. He is your son. DNA does not make a parent or child. He needs you. You are likely saying all or nothing so you can walk away and pretend you tried. Get visitation or joint custody.
sysdmn

If you give up on your wife, totally NTA. If you give up on the child who has only ever known you as his father, YTA. He’s innocent in this, and you’re his parent. Abandoning a child you raised, biological or not, is an automatic AH.
lapsteelguitar

You have a right to be pissed at your wife. But your demands regarding your son are excessive, and out of line. Lastly, regardless of what you may want or demand, the courts will determine what happens next, not you.

YTA

WinterFront1431

NTA. Why is it always the cheaters’ family that think you owe them grace and forgiveness, but if this was the other way around, they would be raining hell on you.

I know it’s painful, but stick to it.

hideme21

Forgiving her does not mean you have to get back together. It’s just acknowledging her mistakes and how it impacted you. And you don’t have to do that until you have processed those emotions.
Pure_Air2606

Stay strong my brother, you are doing the right thing, there must be consequences for her actions, she just wants you to pay for everything, if you ever do decide to stay, ask for a post nup
Fastness2000

He is your son in all the ways that matter and he loves you. You love him. You never need to see her again, you can get the lawyers to stipulate that. Do not give up on your boy.
mathew6987

YTA if you leave your son behind and abandon him, end of sentence full stop. You don’t get to abandon a child and not be an asshole no matter what circustance led you there.
jedivizsla

NTA – you have the right to walk away. She made her choices and now she has to deal with the consequences. I hope you can heal from this one day.
BrownHoney114

They’re disgusting, foul people to suggest You raise another man’s child conceived and born, and fraudulently passed off as Yours. Best to You.
WhatDoesThatButtond

NTA and it’s absolutely crazy you’d be milked for child support when the child’s biological father is still alive and out there somewhere. 
rocketmn69_

It sounds like her family, especially her sister, who knew all along about her cheatung and the son not being yours. They all betrayed you
random_characters42

NTA with your wife.

Definitely TA with your son. Penalizing him for something his mother did.

Tough situation. Good luck on custody.

_MadamMaterial_

I feel so bad for the kid with two selfish, cruel, and truly asshole parents.

He deserves so much more than either of you.

Temporary_Alfalfa686

I’m sorry dude. What the ever loving fuck is wrong with them? To them it was years ago to you it’s right now. 
temptaationelegant

This is a painful situation, and you’re right to seek legal advice. It’s a tough road, but you’re not alone.
Cybermagetx

Nta. Paternity fraud should be a crime everywhere. I feel for the kid but wife can go find the bio dad.
Sensitive-Specific-1

NTA . Of course she wants you to stay and pay for her lifestyle , but why on earth should you?
Clean_Factor9673

NTA. Your wife needs to realize she made a choice to betray you and have another man’s child.
jimjim55555

It was only a mistake for two reasons- 1. Because she got pregnant, 2. Because you found out.
Kindred069

Not your son. Wife cheated. Time to leave. Kid is NOT your problem op. Good luck. Nta
Ilovepunkim

NTA. That manipulative cunt doesn’t deserve another chance. Put yourself first.
SignificantOrange139

>Either I get full custody or I give up on him

And that’s where you lost me.

Bartok_The_Batty

If he’s not yours, why would you want full custody? To punish your ex?
Fatwu89

No judge should ever allow child support if there ispaternity fraud
bubblewrapstargirl

Get a court ordered paternity test as part of the divorce.
UsuarionoAnonimo

What a despicable woman, just like her family.
frozen_pipe77

All or nothing with the son is ass holey

Conclusion

The original poster (OP) is grappling with a profound betrayal stemming from his wife’s past infidelity and the subsequent revelation that the child he raised is not biologically his. Despite his decision to leave and seek divorce, his primary motivation remains concern for the child, leading him to attempt continued involvement. However, the wife and her family are actively pressuring him to stay and reconcile, arguing that the established peace and his love for the child outweigh the past betrayal.

Given the OP’s firm stance on divorce but his conflicted feelings about abandoning the child he loves, the core question remains: Is the OP justified in prioritizing his emotional need for separation and truth by leaving entirely, or should he continue to sacrifice his personal integrity for the sake of maintaining a stable, albeit fraudulent, paternal relationship with the child?
