Should I cuss her out and if so then how?

Bro listen to me. The best thing you can do is live an awesome life with an awesome girl that isn't her. Don't cuss her out, act like you dont give a **** and it will drive her crazy. I've had a similar thing happen to me with this one girl. She broke my heart twice and i never mistreated her once. When your around her be happy and outgoing and you'll get your revenge. Believe me, she'll regret playing you. It's her loss, not yours. You deserve better.
