What should I do?

there's this really cute guy who i always see around campus. i saw him last year a lot, like EVERYWHERE i went. never sure if he noticed this too, but i could swear that his friends were delusional and seemed to think that i'd been following him or something, because i felt like his friends or he would look at me and laugh. maybe i'm crazy.

this year, i see him more and more. we've been in situations where we COULD have talked, but hes either with a friend or on the phone or working in an office. i even saw him at an appointment with a counselor who he was also going to see at the exact same time, and he let me go first, but instead of talking to me he just was like "i have some reading to do" and went and sat by himself and read a book... yet when we've been in the same place, hes tried to talk to me but seems nervous or like fumbles his words or speaks very fast. what is up with this guy? would it be weird if i bring up that i see him all the time? or should i just ignore it
