@get Tell her now she gets neither. Block her number. Cut off all contacts. Have as little to do with her as humanly possible. If you have to see her in person, be as emotionally distant as you can. Be her "one that got away."
If she's going to manipulate you on this level, manipulate her back. Your presence, your being there is how you let her win. You have a checkmate and it's depriving her of time and attention.
