How to not hate my baby daddy?

Okay. I'm 37 weeks pregnant and My babies father and I have been apart for about a month now. Before when we were together we'd hardly speak and he didn't really seem to care much about the baby. Now since I'm closer to my due date he's texting me asking me how I'm doing. I find it irritating. If I just ignore the message he will call me and begin blowing up my phone saying I'm going to keep the baby from him and cut all ties. I simply reply to him that she's not born yet and nothing is happening which is why I'm not contacting him. I tell him over and over that I'm not going to keep the baby away from him but he insists I will. I don't know if I will be able to even be around him any more because he irritates me so much! I mean I have no issue with dropping my daughter off but as far as spending time with him? No.. and just knowing he broke up with me because he basically just didn't want me, but stayed with me for sex disgusts me..  I hate the fact that I had to have gotten pregnant by him. I hate the fact that him and his family talk so badly about me (I'm sure). I hate the fact we can't be a family, but I'm trying so hard to push the ignorance aside and be cordial with him. I just don't know how..
