Chickengal505, I know it seems really hard right now to see it this way, but life will go on. I promise. With Facebook, Skype and all the other ways you kids can keep in contact, I don't feel you'll no longer be in touch. Granted, you can't be WITH each other, but you can still "be there" FOR each other throughout life. I'm sure he's not happy about leaving you any more than you are about him leaving either, but if he hates the area THAT much, I'm sure you want to see him happy.
Enjoy the time you have with each other. High school is a whole different ball of wax and I'm not saying you're going to "replace" that friendship, but you'll find MORE friends along the way. And hopefully still be talking to this friend of yours.
Is he having to move because his parents are relocating?
