need advice

My so is very verbally abusing and we've almost split up numerous times. I left him in July because of it but he begged me to come back. We have a 19 month old so it's really hard to part ways plus we do love each other. He gets nasty to me when I irritate him and then explodes, name calling, threatening ... u name it he does it. I found out I was pregnant again and was happy at first, until we got into a fight over me giving him attitude over something he said and he flipped out. The likelyhood of us having a healthy relationship is slim, I have no family here (I'm from another country) and now I dont think it's wise to have this baby with him. He says if I abort we're getting a divorce. I don't know what to do. I can't see the baby making us better, only worse. Then I'll be stuck with 2 babies and no family to help me. I need advice.
