Baby Daddy wants to move back in with me when I'm about to have the baby!?

I am now 9 months pregnant and been doing this pregnancy by myself because my ex doesnt' want any part. We where not together when I got pregnant, so I accepted the situation, in the beginning he accepted the pregnancy and and changed his mind several times, saying he wanted me to get an abortion which I refused to have. About three months ago, he was really mean and cruel with me, telling me he never cared about feelings before I got pregnant and don't care now that I'm pregnant. I said I was done with him and cut off any communication, because that really hurt and I feel like right know I don't need to be disrespected or put down or rejected during this pregnancy for my baby's sake and mines, so I let go and have talked to him in about 3 months. I have been doing really good at accepting the fact that I may be a single mother, and have done everything by myself. I found out recently that he was married and was happy on his Myspace. I knew I had to really let go. Well this weekend he called me out of the blue asking me if he can come back and live with me for about a month or two. I asked him what would his wife think about that he said that he is not married, and they are not together, his ex wrote that on his page. I asked him why he wanted to come stay with me and he said he need time away for awhile. I don't know what his intentions are for wanting to come back to me. I told him he hasn't given me any reason to say yes, come back with me and the baby no apology or anything. He said he wants to talk in person, so today he wants to come by and talk to me and I dont' know if I want him to come back after all of that, but if he comes back right then maybe will forgive and reconsider. Please give me some feedback on what to do? Confused
