I don't know exactly. A lot of stuff happened at the same time and even now (10 yrs later) I have some troubles pulling the threads apart.
I very mistakenly and now regretfully believed that I should keep my doubts to myself and a few JW adult friends and away from my children. When I realized what an ass I was and how damaging that sort of hypocrisy is on children, I left in a rush with some hopes of redeeming at least a little bit for the kids. Too late though most of the damage was done.
We had a crew of 6-8 dubs that regularly got together and trashed the GB and local nitwit elders. Really great fun. Side-splitting humor. I still laugh to think of some of the jokes. Yet, of that crew, I'm the only one who left so far as I know. I don't really know why I had the gumption and the others didn't. And I certainly don't condemn them. They all have good reasons to stay.
I think it was near-run thing for me. I could easily have stayed had things happened even a little differently. But boy am I ever glad to be quit of that craziness.
On the other hand, one more lesson on the 'generation' and tacking - or one more talk on not whacking off might have pushed me one toke over the line and postal. Who knows.
