So me and my boyfriend are in high school and his ex-girlfriend is a year older than me. Every time she sees me, she gives me dirty looks, says something rude or tries to push me. My boyfriend doesn't believe me when I tell him all of this and he just says that "she wouldn't do that." What should I do about them?

So dirty looks, saying rude things, and maybe pushing you makes her a psycho?

Anyway... why did they break up?

So you tell him and he doesn't believe you. Are you maybe embellishing what she does? You could ignore her or you could break up with him.

What do you think your boyfriend should do about it?
Tell the girl to leave you alone. Ignore her when she's rude but if she touches you report her. Your boyfriend is calling you a liar, that would bother me. He'd be gone. How old are you guys.

Its not just that. She always spreads rumors and she keeps telling me to back off him like he's her property or something. She always does stuff like this. And no I always tell him the truth about her.

How old are you guys? I'm not saying you're lying but your boyfriend is saying you are. Why does he not believe you? Ignore her.

Lots of guys don't like unpleasant confrontation. She isn't his problem anyway; she's your problem. He's done with that relationship, so be glad that he isn't in the middle.

Next time she touches you or even bumps into you, stand back and say very loudly so everyone can hear, 'Trashing on me isn't going to get him back. I'm sorry you are hurting, but leave me out of it.'
