How do i get my really good friend to stop liking/stalking me?

This guy sounds like he wants everyone to know he's ociated with you and he's very verbal about it. He's probably wanting to be more than just your friend, more of a boyfriend, and wants people around you to see him making a fuss over you. Best thing to do is sit him down in a one-on-one and get the real story from him, if he likes you romantically or not. Then go from there. If you don't want romance with him, then just say so, and tell him how uneasy he makes you feel in the way he acts toward you and around everyone. If worse comes to worse, tell him you'll get a restraining order put out on him from the police to prevent the stalking and such.
