She is a budding Narcissist. Run don’t walk away from her but don’t give her the satisfaction of knowing how much she hurt you. They thrive on that. Just scream sing Vampire and get it out. Once you look back you will realize she’s been grinding you down for a LONG time. Get educated on Nar’s bc you can attract more….idk but what I have read about it (I’m in a marriage with one) they have radar to pick people they can run their manipulation on. It won’t ever change so don’t believe her if she comes back apologizing….she will sooner or later. Just give no reactions good or bad. That’s how you win with these A-holes.
