He's ending the marriage because in the last year there was no more sex involved due to the fact that there was a lof of conflict in the marriage because they both had kids from previous relationships. Wasnt working out because the disciplining was only working on one side, his kids were being disciplined but hers got away with lots cause they wouldnt listen to the stepdad and go running to the mom.
I hate to be super harsh, but you FELL for that line of bull sh!t? I think you need to move on before you get even more hurt. He's PROBABLY not ever going to see you as relationship potential because you were willing to basically start seeing him before he left his wife. He took advantage of you, and he will cheat on you or whatever, just like he did her. I get the feeling you are really only getting his lame a$$ version of their divorce. I'm willing to bet he cheated on her a lot and not just with you, and he PROBABLY got caught... Even if you didn't have sex with him when he was with her, it's still cheating.... if you know the man is married... LEAVE him ALONE! Period. You do know she can sue you for alienation of affection, right? It's a big mess and not something anyone should have to put up with.
