Trigger warning

So my husband beat the crap out of me yesterday on the way home from the hospital. So bad i turned the car off while we were driving to try and jump out i have bruises all over my legs arms the back of my head and the top of my tummy i am also 32 weeks pregnant. And for the past few months hes been "poping me" in the face saying its not abuse and for the past 8 months hes been emotionally abusive cheating on me and doing drugs. He says i deserve it because i make him mad. That because ive artcked him before that we are even ( i would bite him any time he would hold me down because i wanted him off me) he says im over dramatic because im into BDSM it shouldnt hurt me. I am to the point that im terrified of him. Due to him threating to break my arm or dump my body somewhere. I honestly want to tell someone and get him tossed away into a hole but i would have nothing and he pays for my medicine that keeps me alive and pays for food and i cant work so if i do that it would go back on my dad to support y child and me and thats not fair he already works himself really hard. I dont know what to do
