Should i just try to move on?

Okay so i'll try to keep this as short as possible, this past summer my friend and i kissed on several occasions. He told me that he really liked me and that he thought i was perfect, granted he was drunk at the time. In august he went back to his boarding school in ohio. We would talk on aim or text almost everyday. He came back to visit during thanksgiving break. He came over and said hi to me at a hockey game, later we hung out and kissed. the next week we were supposed to hang out but he blew me off, that tuesday returning from break i discovered not from him that he was back at my school. He doesn't acknowledge my existence at school, not even a head nod in the hall. he doesn't reply to texts or ims. What happened from thanksgiving to now? Should i wait a couple weeks and try to talk to him again (i haven't tried to for a few days now) or just move on?
