How do you know the difference between a crush and a best friend?

This is quite the blurred line territory when discussing close friends of the opposite sex and whether or not girls and guys can be just friends.

I'm wondering how you can tell the difference if a guy is just extremely comfortable with you as a friend, and therefore free to touch flirtatiously, hang one on one, etc with no romantic feelings, or if there might be something there.
