I had a friend who DA (disassociated) about twenty years ago. The elders tried everything to stop that. But my friend was adamant.
Then about ten years ago they said to me they should have faded like me and not DA themselves because it would have caused such less hassle with all their JW family over the years.
Then a couple of years ago my friend suddenly decided to get reinstated.
I don't know how long they will last in the all new borg after being so cynical about the religion, the elders and the members of the congregation.
I guess what I have noticed is that things change, people change and you can never really know what is going to happen, or what's going on in someone's head - even if you think you know them very well...
Leaving the jw cult is not easy - it's damn hard - and the jw leadership have certainly made it that way.
