Relationship

WHY would you do that?

This is all one sided.

Find another guy; he's not free.

Use your common sense. There's 3.5 billion other males to chose from. Pick one or two that are available.

A relationship occurs when more than one person is involved. You have a crush.

Nothing. If you feel the urge to do something, stand on your head, which should provide more oxygen to your brain and thus allow you to think straight, at which point I'm sure you will realize that what we have all told you to do (nothing) is the best course of action.
