Need some opinions about father seeing child?

Hi everyone. Sorry I had to create a new account & re-post this question as something stuffed up with my old one. Well I am 17 and pregnant. The father of my child said he wanted me to get an abortion in the start & was really pushing me to get it. I told him it would never happen & that if I really can't keep my child I would put my baby up for adoption. He disagreed with adoption & was still pushing for abortion back then. Anyways now I know that I am definitely keeping my baby also I am too far along for an abortion so he stopped pressuring me about it. He is upset about it still but he was still by my side for a while but he hardly would talk to me or come over, until a few days ago I found out he has been cheating on me since I was pregnant. He admitted it & I have ended it with him & have told him he can see baby when he is born anytime he wants. The thing is I don't want my child to see him though. The father is the partying, show off type. He has an involvement with selling drugs but does not take them. & I just think he won't be a good father figure. Also when I was around 4 months pregnant he told me that I may have a virus called candida from him which my doctor confirmed I have got it now. He seemed happy because that might make me have to get an abortion or something. I guarantee that he will come & see the baby for a few months then he will slowly start disappearing. I want to take my child away & move to Australia where there are better opportunities for both of us in the future. But I know I am being so selfish if I take off with our baby. I am really stuck. After the birth should I take baby and leave? Also I just don't want the father around because I know he won't visit the baby when he is older & he's just not the kind of person I want my baby around. I don't want child support from him or anything too. I work very hard for my money, while he sells drugs to get money.
