Do NOT "let him down easy". Be sensitive to his feelings by not being a cold-hearted bitch about it, but tell him the full, hard truth of how you feel, and leave no doubt for the future. If, after being crystal clear, he STILL doesn't get it, then you are justified in being a cold-hearted bitch (some guys ONLY hear the truth that way).
By letting a guy down easy, you make him think that he's still got a chance, and he'll just keep trying to figure out how to either improve his odds or how long he has to wait in order to win you over. Don't be this girl:
