You have finally shown her that you will NOT tolerate or be with a woman who shows she does not WANT to be with you and will do the necessary things that a woman WANTS to do for a man she loves and respects.
She is now subconsciously respecting you more because you have found a backbone. She was DYING for you to do this a long time ago. Women respect men who don't let them walk on them and are willing to risk the whole relationship if need be.
Keep rejecting her. Don't be mean. Don't be punitive. Leave her alone. Let her think and believe you are HAPPY to be free of her and have had an awakening and she MAY have lost you for good and that now you are giving your great self to someonge else. (the competition)
Life is good. Have fun. Party hearty. Laugh. Enjoy the moment. Social interaction. Let them chase you...
NO backslides such as asking her to come home.
No response to her latest attempt. Keep her wondering and in the dark on why the change in demeanor. Seems to be working brilliantly. If not. Who cares? You have better fish to fry.
