I'm glad to hear it's over. "Friendiness" didn't work and you two continue to fight, push each other's buttons, and wear each other down. It's far from healthy. But even though you've claimed you'll never speak again it seems she's still in there. Anger is part of the process. But you must understand she can't hurt you anymore if you don't let her.
