I'm done

So my bf left me 2 days ago went out yesterday did alot of drugs and came back at 3 am earlier and I told him to leave I live with my mom and stepdad n brothers n sister. He didnt want to he was making a big scene n crying n stuff n just being so dramatic n bringing up old guys I used to talk to. Well back when me n him were dating I used to tell him stuff because I trusted him n I told him about how my mom was talking to an old ex of hers n how he had sent her money one time n my stepdad not knowing. I shouldve never told him because he was like if u leave me I'm telling ur stepdad about ur mom talking to that other guy, which she doesnt anymore it's old news. Idk what to do hes here asleep n smells bad even after he showered he has this smell he always has after doing coke n supposedly he did other drugs too which DISGUSTS me. He doesnt have any family here since hes here illegally from Mexico. I think he just wants me because I'm from here last time he was like I always wanted to be with a girl that's from usa. Ugh I feel so bad for my baby for stressing n also he basically raped me earlier because I was telling him I didnt want to so I hope it didnt harm my baby or I hope she doesnt get any drugs from his system onto her since I'm pregnant. I just hope God helps me because I dont even know what to do anymore, I dont want him to say anything about my mom but I also want to protect my baby... Pls no hate. Also I'm 17 n hes 22 so idk If I would get in trouble if I report him since I'm younger. I have tried to scare him with me going to call n get him deported but he doesnt even care. He just says ok do it its gonna be a free ride back
