How do I tell him.

Sticking to the thought of getting over"him" I've found some one I think i like but I just dont know how to tell him because I think he's already sort of involved with someone. But i could be wrong. There is hope in this situation and that's a good thing. i just have to find the right words and the courage to tell him my feelings. But I think we need to get a bit better acuanted before i'll do anything but it's comming along.
