Marriage troubles

Marissa
I'm almost 29 weeks pregnant and my husband has completely changed his demeanor towards me. He wont look at me, touch me, or even hug or kiss me. He's constantly belittling me and then basically kicking me while I am already down. His drinking has increased so much that he keeps a bottle of vodka in the spare room and sits in there and drinks for hours. I tell him I'm concerned about him and the drinking and he deflects everything on me and brings up petty stuff from a year ago. At this point I know I can't make him change or love me, so what do I do? I can't leave, at least not right now because I'm unemployed and have no family, no parents, no one. Any advice would be much appreciated.
