Help ASAP please?

So there is this guy I really like. He is going to a far off college in a few weeks. My friend told me that he really likes me, but knows it would hurt the both of us to have a relationship because we wouldn't be able to see each other. He doesn't want to tell me how he feels. After college, he wants to chase his dreams, off in Japan. My first question, does he ever want a relationship with me or what? I do not understand why he won't even bother with what he feels. Second, What can I do while he is away to keep him from liking some other girl? I am very nervous and sad about what could happen
Help ASAP please?
