I agree with with heidu. I will add that if he feels it is ok to treat another woman as a breader for his race and nothing else then he doesn't have an appropriate appreciation for women as a whole. You deserve better. Either he is a creep for only being with the other woman to make his babies or he is a creep for lying to you about his real relationship with this woman. Either way he isn't a man I would bet on for a long lasting loving relationship. Sorry if I am being too blunt. I just know that there are a million other guys out there that would treat you with more care and respect. Also you have to think about what happens when she does have his babies. I am assuming that he is going to want to be part of their lives which means she will be part of your life...forever. You can't have kids and not have anything to do with the mother. It just doesn't work that way.
