Most Helpful Guy
You could always get a mutual friend to say something to him. I had that happen in high school a couple times and it's not a big deal at all, didn't affect my view of the girl.
A guy is either going to be interested or not, some don't have the guts to make the move until they get some reassurance and a friend telling him you "like" him will give him the green light. After your friend tells him, if he asks you out then he likes you and if he doesn't then he doesn't view you in that light. gl0
