If you're upset enough to write a page here on this website, I think it is definitely worth it to tell him how you feel.

But how do you tell him? Timing is critical. You need to do it at a time when you're both (relatively) alone, not rushed, and you're not angry at each other. Then you can start by saying, "You know, you really hurt me the other day..." and go from there.

Hopefully he listens to you and apologizes. If so, then as long as he doesn't keep hitting on your friends, things should be ok.

But if he doesn't apologize, or he won't listen, no matter how much you like him, you should move on. If he can't respect you, you'll only hurt yourself more if you are with him. Of course, you can't stop liking him-- you'll just have to wait for your feelings to pass-- but we all have crushes from time to time that are no good for us. It sucks, but that's life-- you deal with it and move on.

If you can't find a private time to talk to each other, try writing him a letter, or an e-mail. Take time to make sure you say exactly what you want, and after you finish writing, you might want to consider waiting a few hours and then looking over it again if possible.

I hope this helps.
