Yes...
He was my boyfriend for about a year and we kept breaking up and getting back together over that period. But then, when we were in seventh grade, we were at a party for the winners of a boxtop contenst in the gym (the prize was playing kickball from about sixth period until the bell rang or something) and me, him, and another student got into an argument and my ex left with these words:
"See you later, you whore."
No matter how many times he apologized, I wouldn't get back together with him. It took a few months before I finally got him in trouble for it(he called me a whore three more times in one day at the end of the semester---I hit him with my shoe and he threw it into the bleachers). One of the gym coaches said he was probably just playing but I knew better. Finally I told the vice principal(I'd told him a thousand times before and then we finally got a witness---I think my current boyfriend).
He tried to constantly talk to me in the classes we have together but unlike him I wanted to pass. It's amazing he did considering how little of his work he got in. He goes to another school now and it feels weird not having someone to yell at to shut up, that no one cares about Star Wars when people are trying to work, during class.
I still haven't forgiven him for the 'whore' thing.
