How to deal with this crush?

there's a guy who my friends say liked me for a few months now. every time i see him he would gaze at me, stare at me in lectures, and talk really loudly to his friends around me. but he's never approached me.
recently, i got a crush on him too. see, he's the kind of guy who's outgoing and makes a lot of jokes and i just think he's funny.
however, since i showed no interest for so long - and since i'm pretty shy to talk to him since we don't know each other at all - i'm not so sure he likes me anymore. this whole week, he's only glanced at me or seemingly purposefully avoided looking at me.
should i move on with this crush? we really dont know much about each other but i think we would get along if we had to talk to each other.
