I was unloading the car. She rudely pounded on the church door. It’s likely I’ll get the silent treatment. I hope so. I can send her email to the junk folder. I won’t block her number unless she turns abusive.
EW Gal, it sounds as though you have extricated yourself relatively well, and you are out the door and in a position to quietly shut it.
I really don't think this situation would have repaid "honesty" as in "I don't like you and I don't want you around" with anything other than hostility and hysteria. Maybe some persons have nerves of steel and can withstand cries of protestation, betrayal, explanations, invective - but I couldn't. And if I were her, I wouldn't want to hear a list of my faults read out to me either.
You are walking slowly, steadily, and unobtrusively away. Just keep going.
