Legal Question in Family Law in California

The best protection is move out of town. He is not leaving his wife asnd if he does it will be for another woman. If he can cheat on his wife why do you expect him to not cheat on you? Love may be blind, but it does not have to be totally unrealistic. If he loved you he would have started divorce proceedings, and not risk the chance of getting another woman pregnant. I know you do not want to hear this, but that is indeed the best advice you can be given.

You need to file a paternity action requesting he pay child support and any pregnancy related costs. It doesn't matter if he's still married, if he is the father of your child, he is financially responsible. If his wife continues to threaten you, consider filing for a restraining order against her. As for the last name, it doesn't matter what your child's last name is for aid purposes. Good Luck.
