WIBTA if i abandoned my child?

r/

Hello Reddit this a a throwaway account. I am 37m and my wife is 39f. We had been married for 10 years and we have a daughter who is 9f going on 10.

Me and my wife had a fight and she said something about my daughter not being mine I kept a straight face but after she realized what she said she left and went to bed.

I had never thought about my daughter not being mine, but I had to know if she was or wasn’t. Long story short I got a paternity test and I wasn’t her father.

I showed it to my wife who begged and pleaded with me not to get a divorce, but I told her that I was. I told my family and friends what happened and they said I should cut them out of my life including my daughter.

I don’t want to raise a child that’s not mine nor do I wanna pay for her either. My wife keeps calling me telling me not to make her and our child homeless, but I don’t care if she is homeless or not she shouldn’t have cheated.

for people wondering where her real dad is he’s dead, he died a few years ago. so WIBTA if i did just cut her out of my life?
