You make me feel that I'm not worth the inconvenience of me keeping this friend. Anyone who enters my life is in my life forever until they've done me wrong. That's just the way it is.
See the self centered, narrow-mindness in her? The WW can take anything and twist it around to make it sound as if you are the one who is wrong.
She will continue to point out there is no affair and that you are jealous, etc. Stick to your guns. Do not allow her to wear you down. If she doesn't let go of this bone.........consider telling her that you will not take part in a M that includes her past lovers. Then refer to her saying once a person is part of her life, she never lets them go.
She needs to believe she is losing you. Otherwise, she will continue to have you dance to her music.........and if she gets by with having ex lovers as friends, you can expect her to have another affair in the near future.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
