My ex-girlfriend sent me a nasty e-mail. I want to put her in her place?! Help!?

the only revenge that doesnt make you look like a psycho or prooves her right is sucess. When people mess with you and try to bring you down the only way to make them feel bad about it is by making yourself a sucess, then they will look back and know they were wrong,, if you retaliate at her even a bit she will think she is right about everything
