I say it's good. Just let it out.
If I'm interested in someone, I'll let them know, even if it looks like the feeling isn't mutual. There is very little to lose and you might be surprised at what you gain. The key is you can only get away with pulling that stunt once - you bring it up, you leave the ball in the other person's court, and then you just get on with your life. Maybe (and this is a big maybe) 6 months to a year later you bring it up again, but you probably don't because hey, why not just move on to greener pastures.
