What should I do?

So.. I need some really serious advice guys. My boyfriend and I got kicked out of our house because his father and roommate were treating me like absolute shit. The roommate has not only threatened to shoot me multiple time but has threatened to shoot my dog. He has attacked me verbally so many times. His dad has grabbed me inappropriately and thrown me to take the keys to MY car and has verbally abused me as well. They've both told me multiple times to kill myself in front of them but here's the catch.. my boyfriends mom refuses to let my boyfriend say anything and she told us that the two of them are only there because she's allowing them to but she wants us there.. but she kicked us out instead of them. She makes excuses for them constantly. The biggest thing that's bothering me is my boyfriend is still talking to them like normal. I don't want to tell him that he can't talk to his dad (even though he can't stand him) however, I 100% don't want him talking to that roommate anymore. He has not only taken advantage of us and treated us both like shit, but he owes us money as well. What should I do? It pisses me off and sets me into a major anxiety attack to hear either of their names or see their faces. I need some advice because nobody else is helping me. Oh, also, both of them have gone through my shit and thrown things away and one of them used my $300 hair dryer for something and left it plugged in next to the sink for apparently 3 weeks. We are currently living with a neighbor because my boyfriend makes jack shut for money so we can't afford our own place yet, we can't have all of our stuff over here.. we're not allowed to have our dog here either.. which absolutely kills me because since we've left he's acted different. He whimpers when you try touching him and whys away where before he loved cuddling and loved attention.
