I really need guy advice, please help!?

Um, okay so this is gonna sound kind of stupid, i know trust me...so about a year ago i started a new school, and there was this guy there who i really didn't notice much, i mean hes cute but not that stand outish, anyway i kinda thought he was part of that conceded group in school you know?(im in 11th grade by the way) and didn't really notice him much, but i started liking this other guy who i talked to like everyday, and we started going out, but at the end of the year i noticed the first guy looking at me and we made eye contact and all of that cliche' crap..and i havent really been able to stop thinking of him since, i mean weve only talked a few times, and it was only because we had to for school and stuff and when we do i actually go out of my way not to make eye contact with him...anyway i really cant figure out why i like him at all, and im kind of shy so i really havent attempted to talk to him..and i mean he seems a little nicer than last year..but still i really can't figure out any reason why i would like him, and im still going out with the other guy.. does anyone have any idea what the hells wrong with me? lol sorry but its really beginning to bother me because i really do like the guy im going out with, yet i just noticed that it seems like the other guy and i actually kinda go out of our ways between cles to bump into eachother, not even to talk to eachother we just kinda like glance at eachother....help? And agin i know how stupid this soundss :(
