I suspect your stats are pretty close to the mark. I'm quite sure my first wife would have claimed it was mine had I not caught her cheating on me before she could get pregnant. She really wanted to get pregnant and it wasn't happening with me. All I can say is she didn't really push the issue with me very much and she never admitted to that as a reason. She did marry the man she was fooling with had one child a girl. She divorced him after 7 years and a few years after that tried to get back with me. So what am I to think?
