good and bad feelings

i just keep thinking about him and its driving me crazy. My best friend is having some problems she likes this guys but shes worried it will turn out like the other guy, and i´m worried too. i don't want her to hurt, i love her so much i don't want anything to happen to her. i mean i love her to death but yea i hope that this is the guy that's right for her and i hope she´ll be happy with him.
