okay so there's this BEAUTIFUL girl but after this situation, what should i do?

[Robert A]

in august, i noticed this really cute girl in a class of mine but didn't think much of it other then "oh hey cute girl" that was until i noticed that we walk the same route back to our dorms from that class. day after day, after class i would notice her walking back and i would get more and more interested so i did a little research back in my dorm and found out her name and went on facebook to her profile just a learn a little about her i didn't friend request her. My friend about a month into the semester decided it would be funny that he friend request her from my facebook account while i went to use the rest room. only to see a few hours later that the friend request was not accepted. I started to get a little paranoid thinking that this girl thinks that i like her. During the semester she would sit next to me in class several times and it definitely wasn't by chance because we would both arrive early enough to sit wherever we want. So the fall semester goes by and its a few days after Christmas and my friend puts her AIM s/n on my buddies list and accidentally pressed the call button that ended in her knowing that her s/n was on my buddy list. After the confrontation over aim, she basically thinks that I'm a creepy stalker when really, i just wanna get to know her although my acts were a bit stalker status. then i falsified a story on aim during that confrontation saying that it was my friend on my aim and not me when it really was me. she was skeptical of this friend from the start the last thing she said was "leave me alone and tell your "friend" to do the same" So we're in the spring semester now and shes in the same continuing class from last semester as i am. i honestly cannot get this girl out of my head i don't know why i have feelings like this for a girl i don't even know!...I'm just dying to get to at least know her! she probably thinks i like her, but then again she isn't 100% sure and also 'cause of the fact we don't know each other. what should I do?
