Ex girlfriend rant

Rebecca • 17. Getting ready to be on my own. Trying to live the best life I can while battling depression.
So my bfs ex is starting shit saying I'm a whore and a slut because she found out we started having sex. They broke up almost two months ago. And he obviously moved on. She will literally see me with my hand on his knee and burst into tears. she's physco. Like literally. She keeps saying well when he wants me back he will come tell me. Bitch no. Obviously he doesn't want you back. My bf is pretty much hoping if he ignores her she'll get over it but she hasn't. I feel like I should confront her. I know if I do, I won't be very nice about it and I don't even care. She's two years younger than me and my bf and she's so petty. We are graduating this year and she is a sophomore. I can't decide if she's really crazy or if it's because she's going or both. Lol. She is so annoying. She was like oh my god he told her all the personal things about me. And he really didn't. I have no idea what she's even talking about. I just want to tell her to fuck off and grow up and get over herself. Rant over.
