What do I do regarding the birth father after an unhappy pregnancy and breakup only a week before birth?

Originally we planned to have this child together. In retrospect, I believe he wanted to guarantee that I'd stick around which is why he was so insistent on pregnancy. I wanted to have a baby.. or so I thought and was happy to have met a man who seemed to want one with me. Of course as time went on, we did not get along very well as we didn't know one another well. His controlling behaviors (accusing me of cheating and threating to leave me and have with someone else if I didnt have with him) and my sense of being trapped killed the relationship. There has been a lot of emotional blackmail, primarily from his side because he wanted me to focus on him rather than on the pregnancy, family or friends. It is not that I had no focus on him, but what I did was never enough and he did not respect me emotionally. One week before the birth, he broke up with me, but insisted on coming over every day and calling. Seeing as how he was noncommittal towards me and has blown hot and cold throughout the pregnancy, I have ignored his communication. Now that my family is staying with me, he is staying away. I am considering having an adoption because I dont feel I would like to raise a child alone and be a single mother. I am also considering that if I kept the baby, I would most certainly want nothing to do with him. Help!!
