My abusive ex

So this fucker was just abusive in every way besides physical during our relationship that I ended when I saw it this year. We are in the same chemistry class and he had the nerve to ask me to be his friend going on this long shut like “oh I’ve changed, I’m trying to be better, I know I messed up...” and I just said no like the petty gal I am and walked away instead of calling him out and risking suspension for getting in a fight.

But since then he hasn’t really tried to talk to me but we have two different levels of band the lower one I’m in (Symphonic band) and the higher one he is in (Wind Ensemble) that meet at different periods of the day. Since it’s like the last two days of school and no one is doing anything some kids just walk into random classes to hang out with friends. And he hung out with the only person I really talk to in band the entire time and was forced to be alone. So yeah im a little pissed, I know they are still friends and it’s okay that they hang out whatever but like really?? You know I only talk to her so like why??? I hate this guy so much...
