Ok so through my best friend up school (who is a guy) I met a group of guys who will all eventually be my roommates next semester (five all together.) Anyway one of the guys likes me and even though I wasn't into him, I agreed to a date (back in October) because he's a nice guy and well you never know . After the date I still wasn't feeling him and I told him I wasn't looking for a relationship and that I really liked us as friends. He was cool with it and a couple months went by just fine. Things started getting weird though when I would bring my other guy friends to my house if we were throwing a party. All of a sudden he would through a tantrum about a 'unrelated' issue and storm out. None of my guy friends thought it was weird and eventually I thought nothing of it. On my 21st birthday we went to AC, he came along and everything was fine until we were all getting ready to leave. All my other friends had left and he stuck around and asked if I wanted to get lunch. I told him I had other plans and he said he'd tag along. Nothing I said convinced him to leave, and eventually with extreme annoyance I allowed him to come with me. We were walking back to the parking deck when he told me he had a present for me. I opened it to find that it was music festival concert ticket that's worth somewhere around $280-300. I thanked him but very nicely said that I couldn't accept it. I gave him a hug and he tried to kiss me, no big deal, I just laughed a little and told him I had to get going and I thanked him again but respectfully declined the gift. He said he understood and went to give me a hug. I hugged him but he tried to kiss me again. This time he didn't let go, still laughing I pushed him off of me and turned back to my car. He grabbed me from behind, not too hard though, and whispered in my ear "Do you know what other girls would have given me for this?" Still laughing but in a nervous fashion I freed myself from his hold but he grabbed me again and said "blowjobs." Shocked I completely pushed him and went over to my car. He ran over and stood in front of it and I begged for him to move. After about five minutes he seemed to get the hint and said "ok fine" and moved out of the way. I opened the door and was about to start the car when he jumped in the driver seat with me and tried to kiss me again. He sat there for exactly 12 minutes randomly trying to rub my back and tickle me. I know this went on for 12 minutes because I was forced to stare at the clock because when ever I looked at him he would say "see, it's a look like that..." and he would lunge at me trying to kiss me. I must have said no and that I had to leave twenty times, I even started to cry at some point. He finally backed off when on his last advance I screamed as loud as I could. When he backed up, I slammed the door and drove off. What scared me the most is that he was smiling when I drove off... like he still didn't get it. I told my best friend and the other guys what happened but none of them thought it was a big deal, so I decided to not harp on it. In general he's a nice guy, he just didn't get that I wasn't into him- acted extremely inappropriately. So for the rest of the semester, I avoided him and made sure if he was at the house that there were other people around. Everything had been fine since, until last week when I found out he had applied to the place where I work for a job. The reason why I found out is that one of my friends over heard his interview where he adamantly told my boss not to tell me he was applying. He wanted it to be a surprise. Ok so my question is... am I overreacting? I mean there were a lot more little things that happened but they're all minor. And if I'm not overreacting... what else should I do?
