How To Get Your Ex Back!!!

Shes known him a few months longer than me because he knew her older brother from go cart racing. He told me lots of stories of her going really fast to get him and actaully asking him to make out. I never had a problem with her liking him before but recently i could’t stand it.
She texted a few days ago saying he should break up with me and go out with her. He refused and then she said they could date without anyone knowing. Normally I would just make fun of that. But it makes my skin crawl how she pretends to be a friend to me in school by talking to me and complementing me but in reality she does that shit behind my back. Even a month or so ago when she knew me and my bf were together at a grad party she kept trying to sit on his lap and makeout with him.
How do I get her to back off without losing my control and kicking that miget b*tch in her short a$$ teetth.

truly, your bf will have to be the one to put a stop to it. having him confront her will show that he values your relationship. you’ll just come off like a jealous fool with no control over your man if you try to "talk" to her about it.
