Help...

What do you do when your boyfriend wants 5 days of not talking or communicating? I don't how to react or what to think. We're a long distance relationship. I just started school and he got a job that he enjoys. He just hates that we can't see each other as much as we used to during the summer. This is not the first time he's been like this where he's had doubts or has been like this. Every time this happens I feel like I'm having to convince him this relationship is still a good thing. I just don't know what to do anymore...
