I REALLY need advice right now!!!!! What should I do!?!?!?

if i were you i would either, if he was with his friend and started saying ewww to me i would walk up to them (looking pissed off or a polite smile) and ask them both what their problem was, and ask the friend why do you hate me or tell him he is a jerk. and tell the guy you like you are disappointed in him and thought he was better than that. and walk away without looking back (make sure you look hot that day if you do this) and if he was alone i would just flat out ask him what was his problem and if i did something to offend him in some way. but in my honest opinion he is not worth it. (you could try ignoring him that sometimes works)
