I have the same problem. My boyfriend now lives two hours away from me (i just moved to college) and neither of us has reliable transportation. We talk on the phone almost every night however, which is hell on my long-distance bill. A suggestion I would make is that when you start thinking about him, if you can't give him a call, then write him a letter. Pop it in the mail the next morning, and he'll get it in a few days. It may not be the same as a hug and a kiss, but at least he'll know that you miss him and think about him a lot.
