Imagine meeting a little girl in elementary school, quickly becoming friends, and later dating. If you thought this was the girl you were going to marry, what would you do if you found out she cheated on you with your brother?

In this story, one man is in this position, and he wants nothing to do with his ex or his brother. Now, there’s a baby on the way, and his family is urging him to reconcile.

Let’s read the whole story.

AITA for wanting nothing to do with the child my brother is having with my ex and refusing to acknowledge them naming their kid after me?

I (20m) dated my now ex-best friend Alia (20f) from age 13 to 17. We’d been best friends since pre-k and I adored her. I thought we’d get married as adults and have a family.

But then I found out she was cheating with my brother (19m currently).

My relationship with both of them was over when I found out and it was messy for months.

I don’t blame him for wanting to leave ASAP.

Alia wanted me back. She told me she made a mistake and we were meant to be together.

My brother wanted me to see it as a mistake at first but then he wanted Alia and he told me he fell in love with her and wanted me to accept it and support them being together.

Then Alia wanted my brother. So before I’d moved out they were together and dating.

I avoided them like the plague and any time they tried talking to me I told them to get the heck away from me and treated them like a disease.

I don’t know why his brother’s angry, but OP has every right to be angry.

A couple of times my brother and I almost came to blows because he started getting angry that I wasn’t willing to forgive them. He accused me of trying to break them up.

One time it got really close after a fight because I hoped the two of them were miserable and hated everything that moved until they destroyed whatever love they thought they had.

He didn’t like me saying it but I meant it.

He avoids his brother now.

When I moved out I refused to see my brother after that.

My parents understood but told me they hoped in the future we could be in the same room.

Some family invite the two of us to stuff and I skip it to avoid them.

Other family members invite only me.

It’s caused some tension. I told those people in my family that if they want to invite my brother to keep the drama down I’d see them other times. But I have some really loyal family.

Why should he care about them?

There was some tension several months ago when my brother and Alia were in an accident.

I didn’t go to the hospital and I only called to see how my parents were doing. I didn’t care about my brother or Alia at all.

It rubbed some people the wrong way. It upset Alia really badly too and my brother started talking badly about me to some family.

And then after a while he tried to get a cousin who speaks to us both to mediate for us.

And I told my cousin he didn’t need to because I still wanted nothing to do with my brother.

They should really pick a different name.

My brother and Alia are having a baby now and apparently once they found out they were having a boy they decided to name him after me. This was used to try and bring me back into the fold.

I have some family telling me I need to be in my nephew’s life and I better fix things between the three of us before he’s born.

But I don’t want a relationship with their kid and them naming him after me changes nothing for me.

He doesn’t have to be in this baby’s life.

It’s getting me some trouble from family members who say I should be over it by now and my only brother should be more important than some teenage cheating.

I was told by some people on my side and others on the side of “forgiveness” that my brother and Alia’s relationship gets more strained the longer I refuse to have anything to do with them.

The family on my side tell me as a heads up for dramatic relatives.

The people on the side of forgiveness tell me to shame me for potentially putting the baby through a broken family from day one. They said I wished ill on the relationship and now a baby is involved so I shouldn’t want everyone miserable and I should want a relationship with the child. They say it’s disgusting I’m not willing to put the past behind us so I can be an uncle.

AITA?

This is so messed up. I don’t blame him for not wanting anything to do with his brother or his ex. He should keep doing what he’s doing – ignoring them.

Let’s see how Reddit reacted to this story.

Seriously, how do they think this will end well for the baby?

I would never forgive them either.

This might be what the future holds.

He’s better off staying as far away from them as possible.
