So confused...

This is a sticky situation that someone that I know is in: I have a friend that talks to this girl; the girl is cool and she's not bad to look at either. But my friend has a dilemma...there's this other girl that he likes and feels more compatible with than the girl that he talks to; that girl is just about as good if not better to look at. My boy (my friend) told the other girl that he really really likes her and wants to be with her but he can't talk to her because he already talks to someone. She told him that she really wants to be with him too and she believes that he is like the absolutely perfect boyfriend, but she doesn't want to come in between the girl he talks to and him, even though she once told him that if he feels so strongly about her, then why doesn't he try to do something about talking to her instead of the other girl. My friend told me about this situation and how much stress and thinking it's causing him to do. He really needs some advice so...anyone???

p.s. I am NOT talking about myself. This is a FRIEND'S issue that I'm trying to help him out with so do NOT think that this is about me.
