I would REALLY appreciate some advice on this guy I've liked for 2 years?!?!?!!?!?!?

it kinda sounds like he's a bit shy around you. be more friendly to him and talk to him. if you keep ignoring him then he's probably going to think that you don't like him anymore. from what you say, it does sound like he's giving positive signs. maybe he likes you back. good luck :)
