Problem.

he's is your best friend yet you havn't talked to him in a month?

That stuff happens man, especially if he's been hanging with the wrong people. But when you change the crowd you hang out with, usually that means he's trying to find himself. He doesn't know what he wants, or who he wants to be.

You need to talk to him about the time you met him, and all the fun you had together. Remind him of who he is.

Or it could be just that his friends are dicks, and taking advantage of him.

Either way, you're his best friend, or he's yours, you should talk to him.
