He's saying stuff about me, but I hardly know him?!?

-Okay, So I did have a little argument with his girlfriend a few days ago, who i've known, all my life, but were not that close any more.

But I know he would take his girlfriends side, but ever since, he has been talking about me to his mates (and he's popular, so like, everyone in the year believes him), and he's apparantly been saying some horrible stuff about me, and I did catch him once, talking to a group of his friends and staring at me. That same day, all his mates were throwing chips and stuff at me and my mates, as a joke, but I think he was aiming them at me, on purpose. I hate it! I'm going to loose all my friends if he doesnt stop! He's also mates with my boyfriend too, oh, I am a girl by the way, aha. HELP!If I were u then I would tel my bf wat this guys been doin! If ur bf rely cares for u then hel take care of it!
Get ur boyfriend to beat him silly
