I can't stand my child's father

So this is going to be a long one and before you judge please let me explain. I had just gotten out of a serious relationship and had my heart broken when I met my child's father. I thought he was really nice and could offer me the happiness I wanted. So stupid me jumped right into another relationship (completely stupid I know). Things were ok at first but slowly I started to see the real him. First off he was an alcoholic, his idea of 1 beer was a 40oz. He'd drink two of them in a night. Not surprisingly he got a dui shortly after we met and I became his taxi. He got off work at 11 every night and he would expect me to pick him up from work and take him home (which was 30 mins away from my house). If I was late he would guilt trip me. Whenever he would drink he'd always start these nasty fights with me about how I didn't care about him and how I wasn't doing enough that would end with him screaming at me at the top of his lungs. Eventually those fights would happen even if he wasn't drunk. He was constantly manipulating me getting me to do things that I didn't want to do, causing trouble between me and my family. The final blow was when I found he had given me hpv. I was completely disgusted. I felt dirty and still feel dirty. But his response was to get mad at me and tell me how I should at least try to stay with him and how him giving it to me wasn't a big deal because "a lot of people have it". Fast forward to a couple weeks after I broke up with him. Im moving on things are gettin better with him out f my life....and then I find out I'm pregnant. When I told him the first thing he said was "I want 50/50 custody". Naturally I said absolutely not because he was clearly an irresponsible adult and he had no idea what it meant to take care of a child.  I told him to show me he could be responsible and a good father and then from there we could talk about it. Well not even a month later he gets himself arrested on a felony gun charge (which he will claim is not his fault even though he got pulled over with an illegal gun in the vehicle) on the other side of the country which he drove to on his suspended license. He then proceeded to tell me that he was going to go on the run because he didn't want to face jail time because he wanted to see the baby. He was somehow appalled when I told him that I wanted nothing to do with him if that was the case and couldn't see why I would do such a thing. He has since chosen to face his court hearing s which is good I guess. He wants to be there for the baby and as much as I wish I could deny him I know it's not right. It's just so hard because he's so disgusting and such an irresponsible person who takes no accountability for his actions. The thought of him touching me or being near me gives me anxiety. I have nightmares about when I have to see him again. I'm letting him be at the hospital when Im in labor (he's not going to be allowed in the room when  I give birth though). I'm trying to do what's right but it's so hard he completely messed me up. He couldn't even be here for me if I actually did want him near me. Going through this pregnancy alone has been so hard I've had no emotional support. Im just filled with so much guilt. My son deserves so much more than him and I'm just so heartbroken that because of the choices I made, my son doesn't have a father that's worthy of him. Sorry for the ridiculously long rant.
