I was a first semester college freshman and at my uni it was required for all freshman to take a "freshman class." It was supposed to be freshman only, things like what to expect in college, how to pay bills, sex ed, shit like that. Very small classes, the one I was in only had 8 people in it. He was one of them...but he was a senior and was only in there because he never did it his freshman year and you had to take it to graduate.
He was the boyfriend of a girl in my sorority who had gone to study abroad for the semester. My boyfriend who was a sophomore at a different college was also doing a semester abroad, so we became friends through that. I had a skeevy vibe about him but my bf thought I was overreacting and it would be good to be friends with someone who knew what short term long distance was like too. Camaraderie and all that shit.
A month into the semester my car got broken into and everything was stolen. I was a wreck and my roommate was a bitch so this guy offered to let me come chill and watch South Park and eat popcorn. Okay cool. He had been a perfect gentleman up until this point. We watched a few episodes then I asked if I could borrow his computer to set up a Facebook page for my mom (whole other story lol) to which he said yes. I finished, thanked him for being there for me, and said I was going to leave now. He asked me not to, practically begged, still being super sweet. I didn't want to stay the night and was tired, I just wanted to go to my dorm and fall asleep...I knew my roommate was probably already sacked out. After a few minutes of back and forth he snapped.
I'll never forget the way his eyes changed. Suddenly he was cold, and looked completely dead inside. His voice got deeper and more gravely.
"I said. you're not. FUCKING. leaving."
He saw how scared I was and said I could sleep on the couch. That was the night he first raped me. The next morning he told me I wasn't allowed to leave unless he knew where I was at all times, showed me pictures and was bragging of what he had done to girls before, and told me that if I told anyone or disobeyed him I would get all this "and worse."
I protested a lot that first night, and over the months I protested every now and then even more to see if maybe he would be tired of me fighting him. Every time I protested I got beat. Fortunately he never used the giant flashlight and ropes he kept by the bed on me like he did on some of the other girls. I'm 100% positive that the only reason I'm alive and without a fuckton of physical scars is because I (for the most part) obeyed him and got him to trust me.
As for leaving, I explained a little better in an earlier comment: essentially I dropped out after that semester and never went back.
