Should I tell him I like him?

Okay guys, so there is this boy that I liked in high school, freshman year we had the same health class together and EVERY time I would look up he would be all the way turned around looking at me smiling. I kind of thought he liked me but at the same time he acted like he didn't.. u know, the usual thing boys do. But anyways, we kept in touch and stayed friends and fastfoward now we are in our junior year of college. He goes to school a few hours away and recently all of my feelings randomly came back.. i guess its because we've been kind of talking more lately? but i feel like after all this time he won't like me... but i actually REALLY really like him. I want him so bad. So heres the question, should i tell him that i like him???? or would it be just weird after like 6 years? (haven't seen each other in 3) help!!!!!
