The silent treatment and how it sometimes backfires?

My friends all think I've become too attached to my best guy friend who I have a crush on. He has a girlfriend back home (4 hous away) and we spend all kinds of time together. Usually we talk for hours every night until around 2am when one of us caves and says we are tired. One friend suggested I quit talking to him so that I can get on with my life, so I have tried taking her advice. Today is the 18th day since I've talked to him at all and it's killing me. There are so many things I see that I just have to tell him and he's really my best friend because he doesn't judge me or pressure me to do things with him the way my girl friends do. I wanted to wait until he initiated contact to talk to him again, because then I won't feel like I gave in, but I don't know. What should I do? He knows I have feelings for him, but we try to stay friends anyway. Help!
