Toxic?

I dont know what to do anymore, the dad of my kids, my partner, argues with me, says horrible things to me and gets upset with our kids consistently. I am currently 15 weeks pregnant, he ridicules me, calls me names and gives me a hard time with chores and cooking even though i do those things evedyday. Im not allowed to rest or sit when his home, his costantly hounding me to do something even though my legs get so swollen they hurt and argues with me non stop even when i tell him to stop and that my head hurts. Im hurting so bad, my family is just as abusive... they told me to abort my baby when i found out about him. Im in my thirties, i have no one and i dont know what to do anymore.
