<human>: Can you condense the text into a few key points?

I'm a 21-year-old guy, she's also 21. We've known each other around 2 years, and in the last half a year or so became really close friends, mostly through texting/chatting/etc. We're not aiming for a romantic relationship or anything, we're just good friends. 
  
We go to the same college so I occasionally see her and we've taken some classes together, in these times we see each other a few days a week, have a good time together, it's not awkward or anything. We can talk about almost anything, be it something silly, serious, private, whatever. We're great friends, and we know that.  
  
Yet she doesn't want to go out with me. Whether it be watching a movie or having coffee or whatever, she won't budge. She's OK with me coming over to her house or seeing each other at college but for some reason she won't under any circumstances go out with me or any other guy. We've talked about it many times and she always says it's a quirk of hers that I'll just have to deal with. I tried asking her if she fears it looks too much like a date or something but she says that's not it at all.  
  
So, I have no clue. Perhaps somebody here can give me a little bit of insight on this?
