is there a nice way to say fuck off?

i think that the best way to deal with the aforementioned situation is to politely tell him to fuck off. i don't need head games. i don't need apologies. i don't need sympathy. i don't need this shit. i was doing him a favor by talking to him in the first place. and he turns around and shits on me? what the fuck? no deal, howie. go to hell.
