I am in trouble. I know this guy loves me and I am not interested in him at all. He always calls I respond, talked over the phone for very long, I do if he asks a favor.... I want him totally out of my life. How do I do this?

An interesting question.
The easiest way is to tell him straight out, either on the phone, or in a public place. (People are less likely to freak out in public).
If for some reason you think he's crazy / dangerous, then just phase him out slowly. Answer every other call, then every 3rd or 5th. If he asks what's up tell him you've been busy, but keep starving him out until there is zero contact.

The direct approach is the best, however (assuming he's not crazy / dangerous); have enough respect to cut him off cleanly. Yes, it will hurt him; but the long way will hurt worse, longer.
Tell him he's a great guy, but you just don't feel that way about him.
No one wants to hear that, but that doesn't mean it isn't true!

Ask me anything
