How to get my boyfriend to communicate more over summer vacation?

Were both 20 and in college and It's summer break, we live in 2 different states so we probably won't get to see eachother until August 23rd when school starts.

The problem is he never text me first, he never calls and no emails. He is a really great boyfriend in person, but this long distance thing sucks. We've only been officially dating for 2 months (but practically dating since October).

I'm his first real girlfriend and i think he sees texting as a information tool, not a conversation one, so I kind of understand, but I get really lonely without communication of any kind. When we do text it's because I text him first and it's only for an hour or so. If I don't text we won't talk for days.

How do I bring this up without sounding clingy? (Maybe I am clingy, but I don't want to be too clingy) we haven't argued yet and I don't want to start now. I don't think he would break up with me, but I'm so afraid that he will think we should take a break for the summer. He's not the kind of guy to say that, but I'm still afraid.

I know he likes me and I don't think he's doing this intentionally, he is really shy so that might be the problem. What should I do?
