Hey feeling down,
I wouldn't totally dispair. I'm going through a similar adjustment-- my boyfriend and I just started a long distance relationship when he went off to b-school. It's an adjustment, for sure, and life you've said about your boyfriend, he's not particularly good on the phone which adds to the stress.
My suggestions--- you need to define the expectations with your BF more clearly. It's only fair to you (and him) that you both clearly know what the other needs. Before my BF left, we decided that we'd talk every day on the phone, even if it has to be brief at times, and try to see each other every other weekend. It doesn't always work, sometimes we're both busy and can't catch up on the phone, but both of us know that it has to be a priority. And we try to plan the visits well in advance ....that helps me when I feel lonely or frustrated with the arrangement-- I know exactly when I'll see him next. It really helps. Those kinds of talks (setting ground rules, etc) aren't fun, but they're necessary....
I agree that it's hard watching someone starting grad school when you're not. I find myself getting jealous of him and all the new friends and experiences he's having, while my life seems like it's more boring than ever. I can't help but feel like he's having all the fun (although I know he's studying a lot) while I'm drudging through work. I think those feelings are natural.
Also, to deal with the fact that neither of us are great on the phone, my BF and I are trying to come up with other forms of communication. To me, exchanging a few light hearted emails during the day helps (we have a somewhat hard time keeping the humor going on the phone). I keep meaning to try webcams, just to have the visual connection (my sister and her boyfriend did this when they were long distance and it seemed to work).
I guess, just hang in there and try to keep the communication going....this stage is hard in any LD relationship!
