If she is putting the her BF name on the Birth certificate and he does not want anything to do with her then I would not worry about it. Again you and your H are assuming that they are his or could be his. They might not be. Does he still talk to this chick?
This is very tough and not needed right now for you. I would suggest putting it behind you and moving forward.
