How do you get over a guy you REALLY liked if he moved?

Well i really liked this guy a whole lot but its like i didnt know it cause i was denying myself and me and him were really close like ..everyone new that we both liked each other, but we both wouldn't tell each other the truth and then there happened to be a day (which was...5 weeks ago before school ended) and he had to move..he didnt tell anyone..but before he left he gave me two long hugs ..then when he left its like its not the same anymore cause he always holded my hand and gave me hugs and alot more and i feel bad that i kept myself from the truth .....but i want to get over it now cause there's probably no point he isnt coming back and he was the first guy i really liked but i dont want to have to keep thinking and thinking about it anymore. any help please.
