My girlfriends ex is mad at me because i didn't fight him the last time at a football game because i told his friend i could beat him up cause hes weak, and he says i hid behind a wall of girls, which i didn't, they stepped in front of me to defend me without me asking them to. Now hes writing these status's about me saying like "I saw people jump from the world trade center. So sad. Ethan wasn't one of them :'( " and he has this friend that he trolls with. I don't really want to fight him but i dont wanna seem like a wimp. What should i do?
