(writing a story) how to embarresingly break up with your boyfriend?

I'm writing a story and my main characters crush is dating a girl. This girl is snobby and just uses him for sex .... When she decides she's done using him she is going to break up with him and embarress/ hurt him so bad that he cried... He is normally bullied by the other kids at school too... He has adhd and is bipolar in this story... . Then my main character will help him out and they'll fall for eachother. The problem is is that I don't know how she should break it off with him...

try to think of something that would make a man cry... Something super mean / embaressing... Thanks!!!(writing a story) how to embarresingly break up with your boyfriend?
It has to be really public. Like in the middle of a shopping mall at the top of her lungs standing on a bench, or the PA system during the morning announcements. And she has to include some embarrassing detail like his small penis or premature ejaculation or something.



That's how all the cliche movies do it.(writing a story) how to embarresingly break up with your boyfriend?
either cheat on him or break up with him over facebook.....or a strange combination of the two.
Well the old 'your winkle is too tiny' always works, or failing that just spreading various dispersions about his sexual performance.



If you REALLY wanna be nasty tho, have the girl nonchalantly bonk one of his best friends. Or his Dad!
she could tell him something like ';Im tired of you, your such a pathetic excuse of a man. All your good for is getting some. and even then im never fully satisfied... Were through!'; over the intercom at school. That would be bad!!!!!!!
Poke a needle several times through the balloon packs, then write ';it's over ya [insert profanity here]'; on them and have her hang them all over his locker or something
