19 weeks pregnant. leave or stay?

My SO is always telling me I don't work enough. I work 35 hours a week, currently 19 weeks pregnant. Today was the worst day ever. We were supposed to go out for dinner, I was really excited. Without even thinking he calls to work to see if he can work. I got a little upset I mean who wouldn't? He got mad saying I was being a little b, provoking me to hit him by touching me, blocking me in places, holding me down, etc. I wanted to leave so I didn't cause any stress on the baby. He took my car keys, then I said I'll call the cops I don't feel safe so he threw them at me. So I left, he's at work and texted me saying I'm crazy and he's not abusive. That I'm nothing but a b for throwing a fit over a dinner. Idk what to do. Help ladies.
