Someone... anyone... Please help me...

Bfs roommate is super creepy. He is a cop. Racist, jokes about shooting black. He is also sexist, brings girls over and pressure them to have sex and then refuses to take them home if they don't. You can hear them say no stop no from his bedroom. It triggers my PTSD from my sexual assaults and abuse. Josh (bf) spilt coffee grounds on the carpet. His roomie threatened to "mess with his shit". Roomie end up going in my boyfriend's room when we were out, took out all of the light bulbs, took all his pillows, and put glasses on his bed. I confronted the roomie and told him not to mess with my boyfriend's stuff or go in his room. He got mad at me. This guy has also been fired from a pd for showing vids and pics of him and a girl in bed to other officers. He got fired. He also just got fired from a security job and had 2 of his jobs revoked/got fired before he even started for being racist and the boss finding out about his last job. This guy is very creepy.. I assure you if he got me alone I would not come home okay. One of my friends was in an abusive relationship with him and I helped her out of it. I am a my bfs place and the roomie is home and brought his ex over. She told us she has pneumonia and a sinus infection with a cold. Being a nursing major, I am all about prevention. I windexed and disinfected the handles and doorknobs. He thought I sprayed his toothbrush and flipped. I was spraying and cleaning the facet knobs that are at least a foot away from the toothbrushes. I am currently frozen in my boyfriend's bed.. Crying.. Hoping that he doesn't come home.. I was raped and abused during my childhood and get so many triggers and bad vibes from this guy.. Sigh... What do I do...? I just am done with life..
