Question about ex... who is my unborn baby's father... would like answers from women and men! Thanks!?

I avoid talking to my ex but tonight something came up and I HAD to. I dreaded it and with good reason. He treated me like complete $hit! I realize that he does not want me to have our baby but at 8 months pregnant... well he does not have a choice. I have not asked for anything at ALL... and really avoid talking to him. I thought about a couple of weeks ago calling him up and trying to reconcile for our daughter, but after tonight I know that he won't. Why does he treat me like this or why do men in this situation treat women like this? He is cruel! It kills me because I really loved him, and now am actually really nervous to get in another relationship because he was so great until all this happened. What if this happens again? Ugh I am just really upset after the way he treated me. He acts like I owe him... does he really hate me that much or does he do this because he does not know how to react? We are both adults and were in a 2 1/2 year relationship. Just want incite as to why he does this... and is there anything I can do to make him at least treat me decent when we have to talk? I know I am a push over with him because I get sad when I have to talk to him... I don't cry just get sad.
