Babies dad abusive?

I have a 1 1/2 year old and am currently 8 weeks pregnant wotg my second. I have also been diagnosed with a dangerously severe blood clot (dvt) and am limited to what I can do for awhile. I am taking 2 shots a day in my stomach. Anyways, my boyfriend has been very unsupportive of helping me with anything ; one including taking the dog out to pee because with a simple jerk my blood clot can dislodge and go into my lung. I asked him tonight, and he didn’t want to do it. So I asked again. He called me a stupid bitch, put his hands around my neck and pushed me to the ground really hard. He’s Always had a bad temper towards me, to the point it’s scary. He also doesn’t like spending time with me or my child, the only reason im pregnant is because he was so furious at me one night I finally just gave in and let him do what he wanted.. as we never do it. As in ever. He also does drugs, very sneaky, and would rather be with his friends than his family. I’ve applied for housing the past few weeks ago and they said it could take a year + to get into. Plus I have my sweet pets I cant leave. I’m at a loss and just needed to vent
