I found out hubby had a child on our first date, and it shocked the hell out of me! He thought he had told me beforehand -- oops
I'd never dated anyone with a child before, but he was just such an amazing person that it didn't matter. I fell in love with my husband because of who he is, and his son is part of who he is. And when I got to meet his son, I fell for him, too
His son's an amazing kid, and xepherys is an amazing dad.
Also, xeph is still friends with his ex, and probably will be for quite a while. Duh -- she's the mother of his child! Sort of a permanent connection there, hehe. I could've been jealous and seen his ex and son as "baggage" and ruined the best thing to ever happen to me, but I didn't. I'm very glad I didn't.
The point is, your girl's ex will ALWAYS be around, since he is the father of her child, but that will only be a problem for the two of you if YOU MAKE IT A PROBLEM. Same with her daughter. They are part of who she is, and will always be, so you can either accept her (and them) or view her as having "baggage" and ruin what could potentially be an amazing relationship with an "incredible" woman. Choice is yours, dude.
