Dude, get a clue! The real reason he won't move on
Bill: Apparently, his ego is damaged, so he’s having trouble dealing with the fact that you don’t want to go out with him. You could go the sneaky, avoid-him route and change your e-mail address. But unless he’s harassing you, that’s not cool. Your best bet is to set him straight. E-mail him, explaining that you want to keep things on a friendship-only basis. Hopefully, he’ll get the message loud and clear, and you can stay pals.
