stalker out of control

THIS IS GOING TO BE A HUGE RAMBLE. SORRY.
This guy is really creeping me out and absolutely won't leave me alone. sent me a text this weekend that said "hey btfl plis return my calls cuz im so in luv w u," then fucking showed up at my door yesterday 2 minutes after i returned from work (even checked to see if he was around the building when i entered and didn't see him. where he followed me from i have no idea). told him to leave me alone, told him that i didn't feel comfortable around him and that he shouldn't be at my dorm and that i was absolutely not interested in hanging out with him and that i was seeing someone at home.

Today I was walking back from work, not even near my building, and he fucking popped out of nowhere. "Don't you think all these coincidences are signaling like fate?" NO you fucking weirdo. He told me he liked that I was hard to get, a challenge, and that he respects that I have a boyfriend but that my boyfriend is probably fucking some girl right now and that we should just get together for these two months. NO. He kept asking what our plan was, and I said there is no plan, you need to leave me alone, stop following me, etc. He just replied by saying that he likes that I'm careful because he's careful, too, at which point he pulled out his HIV test results (negative). At one point I was so desperate to get rid of him that I was like how do you know I like guys, to which he said, "Ah, that's a fast way to try and get rid of me, but then I'd want you even more." AFDlk;jfne.

There are so many other parts of this conversation that enraged me that I'm not going to ramble about because there are actually too many. He actually had the nerve to ask if we could chat in my room afterwards. We even had this conversation in front of security guards, but they did nothing, and after I left I saw that they were joking around with him about something. I am going to talk to my program supervisors tomorrow because I am scared to go home from work every day, and I have like 7 more weeks here. Sadly I don't know if talking to security will do anything because he is also a student on the campus and has a right to be on it, and I'm also terrified that anything I do will just drive him to try harder and be more aggressive. I just need like a 24/7 body guard or something. Or to get a buzz cut and wear shades all the time.

ARGHhhhhhhhhh.
