Anybody still wonder why men don't call back, after finding out a woman has minor children? Unless there's absolutely NO dad involved, it can be quite complicated. Even then, a man is going to get that "You're not my father," look from his stepkids, unless he arrives on the scene VERY early in their lives.
OR very late. When I married my stepkids were in High School. They were great to me from day one and I love them like they're my own.
