Most Helpful Guy
Tell your guy friend that the other guy asked him on date. If he is a good friend then he will probably tell you to go ahead because the other guy doesn't seem to be interested in your friend.

tell your friend that you don't like him the way he likes you. he might be a little hurt, but he'll have to get over it.
you shouldn't have to be alone forever because u are afraid of hurting him. he'll eventually meet someone else thats he's into. and you'll both be happy :)
