How do u tell a guy that you don't want a relationship with him without hurting him?

I think the significant other lie works well for short term, but if he's stalkerish he might end up investigating the truth to your claim. Better come off and say, "I'm sorry; I like you as a friend." But say it carefully and with the intention in your voice that comes off nicely and not meanly. No matter what you say, though, it's gonna hurt him so you're better off just telling him outright how you feel.

I had to do that once, and I did it just like I said in this post. Except I did it right before he was going to take me out for lunch, which is also bad because I was leading him on before then - but anyway, do it before he believes he has a chance with you. Fyi, the guy never talked to me again. =\

Jam it back in, in the dark.
