Is NOBODY wrong in the post ? POST : Me (25f) and my fiancé (26m) we’re talking about having kids. I told him that, because of the heavy line of autism in my family (2 of my sisters, my mom, grandma, nephew, and cousin have high functioning autism) I don’t want to have kids with my genes, I’m okay with adoption or trying to figure out a surrogate type situation, but, I refuse to have any of my dna in that child. I don’t think it’s fair to put a kid through that since I know it’s very likely.
My fiancé said I was being heartless, he said he wants to have kids that share genes with both of us.
I don’t think I’m being selfish here.

We are both very stubborn people, I wanted to ask you guys what you think? AITA?
