Well done Dan, I can see myself handling them that way had the opportunity arisen.
As it is, I have been inactive/non-attending for years now, but I am sure they have been "watching" me, if I had actively expressed my views to the wrong person again, (I did so once, a friend from my youth who I thought I could trust, and then I got the 2 Elder visit), I am sure I would be dealt with in their usual loving way. Be very careful in future with anyone you speak to, the most I say is "I left for good reasons".
If I were you I would tread a careful path so as to keep your "fade" intact, so as to help your son. Maybe your wife will wake up too one day soon and it will ease the situation.
Well done again, you have handled this so well that you have managed to retain your dignity. It felt good to me to force the point home to two Elders a few weeks back that I left because I am a lover of truth.
Funny, they have not come back to show me that as a lover of truth I should be a JW, because JW's have the truth, why have they not come back ? I asked them to, when they were ready show me it was the truth.
As said above, JW's don't care about doctrine, and I think they have been mind controlled so much now that they really believe that "truth" does not matter, only loyalty to the Borg, (JW.Org) matters.
Good luck for future.
