What is the best way to break up with a guy?

My best friend has been going out with a guy for months but for the past month she has been wanting to break up with him but she cant figure out how. Please give me suggestions. The guy is a real a**hole too hang out around!What is the best way to break up with a guy?
if he is an as*hole then she shouldnt have been dating him that long anyway. but what she should do, is tell him that she needs some space and after that she should begin to act distant and he will get the idea.What is the best way to break up with a guy?
very sensitively. Usually it will affect a guys pride, so if she can find a way around that it would be ideal. Tell her to be honest, to tell the guy that things just arent feeling right for her and that he has to end things before they get any more serious and they are more attached to each other.
How bout just saying ....';Goodbye';...';Good Luck';...turn around and walk away.
Tell her to write a letter and then put t in his locker at school....on the letter write ';We need to break up....sorry but you act like an asshole! don't come up to me and ask why just accept the letter and move on'; that should work...good luck make sure she signs her name on it!!
