I'm going on a date with my bullies crush.
Did you break up her relationship with her previous boyfriend?
Yes, I broke up her relationship with her previous boyfriend
It's okay to want to have a win against a bully, especially if they're trying to make you feel bad about yourself. If that's all you want to date this girl for though then you shouldn't do it, because that wouldn't be a healthy relationship.
It's no big deal to do this just for revenge.
I can understand the pain the bully caused you but you could be causing the other person pain by dating them. It is not fair to date them and cause them the same pain you felt in the past.
