OK take some boxing, karate, kung fu, wrestling, tai kwon doe, or any kind of fighting lessons but make sure he doesn't know. then when your done just defend yourself, don't beat the **** out him him. just block every move & hell see he cant bully you & stop
Be wise. Ignore him. Don't let his insecurities effect your life! Sometimes the best revenge is to smile, walk away, and act like nothing happened. :) It might take a while. But just ignore him/her and just be nice. Show them your better and that your smarter! Trust me, the good side never looses! It always wins!
