I might not be coming back to school

Just leave... what does it matter.

Things like this are hard to do,... but I have found that being direct is the best way.

You might want to go somewhere with just him, and that way you both can talk thins over. Best of luck though, I had to tell my best friend I was leaving midway through my junior year (horrible time to move), but the best way was to just come out with it.

Just first move and then email them to tell em that you'vr moved:)

One idea is to have an end of the year party and tell them individually then.That way you can all have one last good time together.

Just tell them yourself because they'll be upset if someone else delivers the news to them.
