Sensitive subject. Long. Need help.

I know this may cause controversy, but I'm just looking for other people's perspective or personal experience.

So my fiance left me, over a month ago. Cheated on me while I was visiting my dad out of state. Has always been emotionally abusive, but making me feel like I need to apologize for everything. My family has helped him financially, over $1000, and took out credit cards under my name bc he doesn't have good credit. He promised to pay my parents back since Aug, but not one cent has been seen. He hasn't even paid the credit card payments (2months over due). He's ruining my credit!

He keeps dangling me on this string, like a puppet. He knows how much I love him (i keep taking him back or begging for him), he loves me one day, takes it away the next. I have gone through horrid crying and stress that he's put me through, even before getting pregnant, where the scars are apparent. I was rushed to the hospital last week bc of a anxiety attack, from just the horrible things he says. He's so mean and he makes me feel like I'm going crazy.

So anyways, he now says he doesn't love me anymore right now... What ever that means. He promised me and my family marriage, he promised that we'd be a family and that he'd never leave or hurt me again. He wants the child to have his last name and be in the baby's life, but without being with me. I now don't want him to have any contact with me or our child. I'm so emotionally done and all he's given me lately is a mind f***.

I know this way of thinking is selfish, but hes trouble and I don't want him letting down our son with broken promises either. Did I forget to mention he's an alcoholic?

He wants to love on me during the birth, but I'm the only one that's truly in love. He's talking to so many other people. How am I supposed to emotionally do this? What do I do? I'm really scared.
