My boyfriend cheated 5 months ago and I don't think I love him anymore?

My boyfriend cheated on me 5 months ago a week and a half before we got married. I found out I was pregnant so I went through with it. I know that isn't a reason to get married but I thought I wanted to make it work. Now 5 months later, I find myself constantly thinking about it and imagining it and all that and to be honest, it's really made me change how I feel about him. I don't know if I love him fully anymore and I've really realized that this past week for some reason. I thought I was getting over it but now I don't even want to... I kind of want to leave but everytime I try he makes me feel guilty by saying he'll probably just end up in jail if I leave or he starts being so nice that I feel bad like I'm the one who is wrong. What should I do? Basically he cheated on me in my bed when I was shopping with my daughter and he was supposed to be watching my son. I got home and he was in his crib screaming, with a dirty diaper. Then he crashed my car, got a DUI and went to jail for a week before I bailed him out. Now hes facing jail time and missing out child's birth. AND I had to deal with the b*tch the whole night and next day because she lost her keys and was wasted. That's his excuse... he was drunk. What should I do?
