The fear of rejection has stopped many, many people dead in there tracks, you figure out a way around it, and by all means post it. Beyond that, just tell him and hope for the best.
Don't tell him, show him. Actions speak louder than words.
You don't love him, you have a crush. Bite the bullet and blurt it out. If he doesn't feel the same at least you'll finally know.
We're all scared of rejection... but if you don't tell him, you won't find out if he likes you back. :)
Now you know how boys and men feel, that is one of their worst fears. If you don't want to come right out and say it, then ask him to hang out or something, and let him notice your feelings when you are together.
