One guy allways insult make fun of me really offensive at university so I cant avoid him. Having problem with AA cause it feels as Im helping him. Today I threw his insult at him back and stronger. He didnt say anything whole day like he was scared but he talks shit behind my back he even tells about me to his girl that Im offended bitch. Whats the best way to handle his constant insulting? Why cant I AA infront of him?
