Infidelity is one of the worst things that can happen in a marriage, and when a child is brought about because of it, it can make it even more difficult.

What would you do if your Mom cheated and now she wants your help to bring the family closer together, especially with your half-sister?

It is a difficult situation, but that is what this young woman is facing.

She wants to know if she’s doing the right thing.

AITA for not telling my brother’s to spend time with our mother’s affair baby?

My mother cheated on my father four years ago and got pregnant.

My father forgave her and raises my half-silbing as if she were their child.

I’m guessing more people know than she realizes.

She looks just like my mother so only a few members of the family knows what happened.

I didn’t know about what had happened either because I live with my boyfriend, it was my brothers who told me everything.

I don’t blame her for this.

I’m not close to my parents anymore, I’m not interested in being close with their daughter because I’m not going to get into my parents’ drama and toxic relationship, it’s their lives, period.

But when all that happened I was already 25 years old, while my siblings were still living with them when all the infidelity was discovered it was in the house so they saw everything.

Coming to the present: My siblings never had a good relationship with my mother again (no, some families can’t afford family therapy so it was never an option).

Two of them no longer live with our parents and the only one left (he is 16 years old) has come to live with me and my boyfriend.

That is unfortunate for the half-sister.

None of them have any contact with my parents’ daughter or my parents.

The 16-year-old ignored the three of them when he was at home (now I’ve been paying him for the psychologist).

My father and mother have let my brother live with me but they keep insisting that I should talk with my brother’s and make them spend time with her.

I can’t force them to do something they don’t want to do.

It isn’t her role to force forgiveness.

But my father insists that I am the older sister and I should do something for the good of the family since my brothers listen to me.

My mother went so far as to tell me that the little girl asks for us even though we have never seen her.

Even my grandparents are insisting that I should talk to my siblings and convince them to spend time with her but I don’t know what to do.

All my family who knows about this (my mother’s sister and grandparents, the rest of them doesn’t know anything, I think, or maybe they know but they don’t care.) says I’m wrong for not doing my duty as a older daughter.

AITA?

Your Mom messed things up, it is her job to try to fix it (if possible), but remember it is not your half-sister’s fault.

Take a look at the comments to see if they have any advice.

Exactly, everyone is free to choose (except the half-sister).

Actions have consequences, Mom.

The half-sister is 100% innocent.

Exactly, what do they even expect you to do?

Yup, forcing your daughter to fix your mistakes is just wrong.

Mom needs to take responsibility for ruining her own family.

These situations never work out well.
