troubled mind -
You guys handled yourself very well.
Being on the otherside at one time, I could not imagine having someone come back so directly, especially a JW sister. Bravo for you!
Those Elders had several things on their prepared agenda, but the one that was eating at them, and one they will have to answer to the body, will be the Xmas decorations.
You guys gave a convoluted answer. Your husband, said "not me" and you, "none of your business". That's not specific enough to proceed to JC at this time. Telling you to send a letter, no matter how kindly spoken, is an acknowledgement that they have given up on you, but not your husband. You must have been aweful convincing for an Elder to lose it that way. Again Bravo!
Overall, it sounds like you gave them plenty to proceed further, if they want to. But you came across as simply, you just quit the WTS, want nothing to do with it, and more importantly, have found a much better way to live. Having your husband a bit quiet, may give them pause, thinking they still have a chance to save him.
Glad it went so well for you and so bad for them. "Rats! We lost another one"
