my child's father didn't want our son since I 1st fount out I was pregnant....he claims he will take care of the baby once he is born. which idk because if u didn't want him and u still show signs of neglect while he's in my womb what would u mommies think? he's never been to any appointments never called when I had to be in the hospital or anything...but want to start being a dad once he's born...it doesn't work like that...a man is a father once u find out your pregnant...not after birth..smh..I don't want him to be in his life now I just think what's the point.
