Tell him you love him like a brother
wow sounds like he is not even friend materiel , when he approaches you write down the date and time where he can see it and say you're building an harassment lawsuit and your dad and lawyer told you to keep records . guys are afraid of dads and possible jail time
If you can't stand him then why do you even want to be friends with him? Just tell him you hate him.
LMFAO! Tell him, be blunt! "I don't like you like that". Sometimes you gotta be blunt with people like him. Did you lead him on to think he had a chance? Be honest.
