Leaving my daughter’s father.

I’m officially over it. I don’t think I can be with him anymore. I’m about to start my job next week after being laid off for 6 months. I just need to get on my feet before I can leave. I really wanted to make it work for the baby but I can’t stand him. He says such rude and things to me, about my body, my weight. I don’t want to be with a person like this. I’ve asked him to stop but he says it’s his way of teasing. Ok great well I still don’t like it and the fact that you won’t stop doing it is pushing me over the edge. I still have about 25lbs to lose from baby weight. I finally posted a pic of myself with my daughter today and you know what he wrote on there? “Big mama😯” I don’t deserve that. And he thinks I’ll never leave him because I have nowhere to go besides my mom’s house.Which is fine by me. Won’t have to pay rent for a little while and I can get myself together for my child until we can be on our own. I know this is a rant but I’m just so upset. And advice on starting on my own?
