Beating out the competition....

[Twitchy]

Use a boyfriend destroyer:

Oh, he seems like/I heard he is a nice guy. He probably just doesn't/I have heard he doesn't date a lot and is kind of awkward around girls. He probably is just intimidated by you being an attractive, confident girl.

I wouldnt worry about it too much - he will either work up the courage to eventually talk to you/ask you out or you will find someone else who is man enough to.

Hey, lets go over here where it is quieter so we can talk....
