Update/ i went back bc i had nowhere to go. And he did it again but worse like way worse. I ended up calling the cops on him he hasnt gotten arrested yet he has a warrant tho. I feel like i made a mistake. Any one else been thru this? // Okay so a little back story

Im 17, me n my mom are homeless. Shes sleeping out of her truck. I stay (stayed) with my babydaddy in his trailer and its straight up filthy. Like cockroaches everywhere cat piss n shit everywhere trash everywhere like bad. Me and him were addicted to meth (we've been together 7 months now) ive been clean 90 days now im 8 weeks pregnant also. I left him today (for maybe the 5th time) bc he wont try. He wont get a job. He keeps putting his hands on me and its getting progressively worse. He wont clean. Wont help me with anything. Im sleeping in my moms van with her as of now. I really miss him.... I wanna go back but i know its in my childs best intrest for me to stay away. Idk what to do any advise?
