should i continue liking this guy?, advice please! (: Options

so ever since i started highschool, i started liking this guy. and hes the type of guy that everyone likes, smart, athletic, really good looking, and talented. but hes pretty shy. shy in the way that he wont always start a conversation with you, but once you start talking to him, he talks alot. anyways, hes never had a girlfriend yet, just because he doesnt want one? or because he doesnt like the girls that like him? and so, this year, i have one class with him, gym- which is fun, but we rarely talk because i feel like i should wait for him to start the conversation [cause i've started it so many times] and i dont want to appear desperate . i talk to him online, when hes on, and he seems to like talking to me
err i also heard from multiple people saying that was "the least weird" out of my friends [he hasnt met a lot of them though T_____T] and that i was really nice [but he thinks everyone's nice ]
i told a lot of people about this [can't help it ] and they all seem to think that i have a chance which is good, but i cant help thinking if its really possible.
and on top of that i also see him looking at me sometimes, but he doesnt come talk to me? should i give up or continue liking him? because it seems so unrealistic for him to like me if he hasnt liked many people

advice please!
