My husband

I don't know what to do. I have asked my husband for a divorce and to stay  out of my life. I have told him even brought papers out but he will not stay away. I am pregnant now but since I have been pregnant he has been a different person. Never staying home and always with his friends. I talked to him numerous times and told him I would never take the baby away from him but as far as our relationship goes there is nothing I want out of it. He has even stopped acting like he was married. He made the comment I need a DNA test. Mind you he is the only man I have been with. But I told him we would get him one no worries but I still don't want anything to do with him. So 2 days ago his sorry was buying me a car. But I don't want it or want to drive it. I told him he can have it and go away. He said I hurt his feelings and he is sorry. But you should not be trying to hurt you spouse because you are unhappy with your life. I pretty much do everything for him and I. Like everything. And he has the nerve to treat me like crap unless we are around my family or his. He is more loving with me around my family. But his family is a different story.  I am over him and I just want him to go away. I just want to get away. But he tries to make everything ok or makes me feel like he really loves me. But he is bi polar and I want nothing to do with this relationship anymore. If I known being pregnant would do this.  I would have left as soon as I found out. But nope I waited thinking he was just struggling with the truth. I am so done and over this.
