My daughter's father

Right now I am currently in a relationship with my daughter's father. It doesn't sound bad but the details would land us on Jerry Springer. I met him a year ago through his brother. He was living with his mother because he had just seperated from his wife. At first we didn't start a relationship because I was seeing his brother but soon enough due to other circumstances we were together. I always told myself that I wouldn't date a married man but he was seperated and not even living with her. Within the first month of being together I ended up pregnant. At first he was mad but then he got excited about it. His wife didn't start calling him until she found out I was pregnant and we were together. He's got three kids with her so she always uses their kids as an excuse to come over. He keeps telling me he wants a divorce but his wife doesn't so it would end up costing him more than he can afford to get a divorce. He pays her every week child support for one of their kids because one lives with him and the other is over 18. I'm always at his house (I've even started paying his mother rent each week) so his wife knows I'm there. But sometimes I get this nagging feeling that he wants to get back with her but not live with her. I've told him over and over that if he wants I would leave and he could get back with her and he tells me no, that he doesn't want me to go. I'm not sure if I'm paranoid because of postpartum depression or that it's actually happening. My boyfriend and I have even started looking at engagement rings. I just don't know what to do with this whole situation. I can't raise my daughter alone. I know that much because I have epilepsy and not getting enough sleep could cause me to have a seizure. He's a great dad and I also don't want to deprive my daughter of having a father figure in her life. But what do I do? Do I stay with him or do I leave? I'm totally and completely in love with him and leaving him would destroy me. There was one time when I actually locked myself in his sister's apartment and had a knife to my chest because I knew that he was with his wife. It's like I love him too much to leave but do I love him enough to where I will keeping putting myself into this position? Please help me. I cry almost everyday because I don't know what to do.

If you love a man with children, you will have to accept that he has to take care of his children and cooperate with their mother. Trust him when he says that he wants to stay with you.
