So I’m pregnant, due in less than 4 months with my first baby. My BD has a lot of kids whom I love dearly. The thing is, I’m just finding out that he’s been a figure to a child that’s not his because his father was killed. He shares 2 other children with his mom. We’ve been together 4 years, and I’m just learning this. Honestly, idk what I’m feeling to even put it into words. But I wouldn’t have gotten pregnant or kept a baby by someone playing a parental role to a child, when they’re no longer with the other parent. AITA???
