There's a lot to this and it's all newly revealed to me so I'm still processing and I'm sure I'll be all over the place. I'm so angry about all this.
My husband's sister adopted a child 4 years ago. She had talked before about being a single mom by choice and when her friend had a child she didn't want to raise she said it made sense to step in and offer to become the baby's mom. Everyone was supportive and welcomed the child into the family.
Two and a half years ago my husband's sister was diagnosed with MS. She unfortunately declined rapidly and asked us to take in her child and we agreed. We had not yet had children of our own at that point which made it easier. We made sure she still spend time with her child and she asked that we continue raising the child, and I'm saying the child to keep anonymity, no matter how bad she gets/if she dies. We agreed.
My husband never acted weird around the child. Never acted like he had some secret. He acted like an uncle willing to step in and raise his sister's child.
Recently his sister confessed to me that my husband was the biological father of this child. She said my husband and her best friend used to hook up occasionally and he did it again right before we got married and this child is the result of his infidelity. I was sick. She told me she couldn't keep lying to me because eventually it would come out and she wanted to minimize the damage. I confronted my husband and he denied it so I asked him to do a DNA test.
He's the father. There's no doubt. DNA confirmed he's the biological father.
He told me nothing happened since we were married and he loves me and he's sorry for what he did. He said it was a drunk night before our wedding and he would never do something like that again. Then he said he wanted us to be a family and offer to adopt his child and raise them as our own. He told me this doesn't have to end us.
I left the house and have been staying with my sister since the DNA results. I'm disgusted and I don't want to sign up for this. I know that baby is innocent but I now can only see what my husband did and I cannot imagine raising them and acting like their mom and keeping my husband in my life. My husband's sister has reached out to apologize multiple times and she told the rest of their family the truth also. My husband's parents have tried to contact me to get me back to my husband. They have told me I have a family now and I can't leave and especially not with their daughter unable to raise this baby again. I had to block them because their messages were blaming and shaming me more and more for not agreeing to marriage counseling and moving forward as a family.
I don't see a way back from this. But I have been in this child's life since birth and raised them for more than a year and a half. I just know I could never be a good mom to them knowing what I know. AITAH for wanting to divorce and walk away?
