My ex's roommate

He was my ex's roommate. I had slept with him (consensually), but had made it clear that I wasn't comfortable in continuing to sleep together because it was jeopardizing my friendship with my ex. We were parting one night when myself, my ex's roommate, and a mutual "friend" of ours went into one of the bedrooms to get high. I sat on the floor in a corner next to the window and the dresser, while the other two sat on the bed. As soon as we got in the room, my ex's roommate started texting me, telling me how much he wanted to touch me and have sex with me, and that he wished our other friend would leave. I ignored these texts while he watched, and eventually began talking to our other friend. At some point, my ex's roommate got frustrated that I was only talking to our other friend and held his hand over my mouth so I couldn't talk. With his other hand he began groping me. I looked to our other friend for help, but he was laying in the bed asleep. I found out later that he was only pretending to be asleep and was actually watching what my ex's roommate was going to me. I remember sitting there with my ex's roommate's hand all over me, touching and feeling every part of me, and I just hoped it would be over quickly, whatever "it" was. I knew he had a history of being physically abusive, and had even pulled a knife on his last girlfriend. Even after he took his hand off my mouth, I was too afraid to say no. Eventually, I texted my ex, who was in the living room, to come back to the bedroom, lying and saying that our mutual friend was annoying me. I avoided my ex's roommate for the rest of the night, and he ended up storming it if the house because he was mad at me. I told my ex what happened the next day, while sobbing in his bed. I texted another friend to tell her what happened as well, because she was going through her own struggles with sexual assault and I knew she could offer support. She was helpful and supportive at the moment, but the next time she was at my ex's house with us for a party, she antagonized my ex's roommate until he became almost violent. I stood between the two of them while he scream at her, so that he wouldn't be able to hit her if he got to that point. Eventually my ex calmed him down, and then scolded me for letting me friend talk to him that way. For years I remained friends with my ex and was regularly at his house with his roommate, so I tried my best to forget about what happened. After moving away and realizing the extent of what happened and that I was afraid to be alone with men, I started seeing a trauma counselor through my school. I struggled a lot with accepting that what happened to me was trauma, since I have no physical evidence and had spent so long trying to ignore and deny what had happened to me. It's been two years since I started counseling and although still have rough days and still aren't entirely comfortable around men, I've made a lot of progress in my recovery.
