When I first started with the doubts I wanted to make sure I was right. I had to prove it to myself because I had dedicated decades and was not about to just throw it away without being 100% sure. This research lasted a couple of months as I had to be careful about not raising suspicion with the friends (I was a highly respected senior member of the congo that's all I'll disclose). The more I dug the worse it got. By about the third month I was fully convinced I had been made a fool. So at that time I needed to figure out how to remove myself from everything without causing much of a stir. Enter the "fade." So I stopped offering remarks, stopped giving talks (made excuses), and started missing every other meeting. I still had to carry out my congo duties which I did (assigning talks, counseling, pastoral visits, assigning ushers, etc) reluctantly but continued to do so.
This went on for about an additional 2 months and even though I was irregular in terms of meeting attendance I made sure to attend all social activities. Whenever I attended the social gatherings I would immediately pick up on the "vibe" and "look/stares" from the friends that told me just like I attended all social gatherings that I should likewise be able to attend all KH meetings. By this time I could care less and they knew their little insignificant stares and looks were all worthless to me as I was OTWO. These stares just confirmed what I had already learned about cults and how members are trained to make those that are non-compliant feel guilty.
It wasn't until the middle of the fifth month that I asked to speak with a very good friend of mine in private after one meeting. This "very good friend" being the good little company elder that he was asked if it was okay if we were joined by another elder to which I agreed. At this point I feel he knew something was up given my recent "spiritual activity." It was at this meeting that I resigned and turned in my KH keys. Naturally, both men were in shock and asked if I would reconsider and perhaps wait until the next CO visit to see if "something could be done." I understood this "something could be done" as the CO's attempt to make me reconsider. I told them that my decision was final and I wished them the best.
These men knew the impact my stepping down would cause within the congo as I was a very influential and personal confidant of many friends. I would be the first to be approached when members were looking for realistic, down to earth, emotional support. Someone who would actually understand and view them from a "normal" lens and not a WTS lens. But after turning in everything I continued attending meetings perhaps twice a month until I finally quit altogether. I showed up for the next 2 assemblies and 2 memorials but after that I was finished.
I knew I would have to walk away from many "friends" people I had grown up with and were like family. So from the moment I found out it was 100% bull crap I prepared myself mentally. As far as my home, well my spouse did not take the changes too kindly and was completely opposed to me leaving. She felt that "apostates and satan" had invaded me and I was now their puppet believing all the lies and vitriol they would spew on God's only earthly organization. After a couple of years she finally stopped attending as many "friends" started to keep their distance from her even though she never did anything! I know, loving organization right?
So, to answer the OP question; Once I found out it was bull crap I started "the fade" and never looked back. I did not care how people would perceive me as I was not going to continue to be made a fool. There were many heartaches and emotional turmoil but today, I am at peace, and could not be happier. Our home is at peace and although religion is still a sensitive area we are back to my pre-exiting days. As each day goes by my spouse continues to see the org for what it really is. I hope one day she can also walk away mentally.
