Welcome to the real world Aldous and well done for seeing through the charade.
When I realised it was a fraud, I began fading to the point of no fs and not answering at meetings. Eventually I completely stopped going to the meetings, oh my! what a relief that was. When an elder friend called at my house six weeks later, I told him "It (the JW religion) isn't for me". That seemed to stop them taking an interest in me and they just announced at the congo that I was no longer one of J's Ws. That turned out to be the instructions to shun me. So although I was not disfellowshipped, the consequences were the same.
In your situation you may want to take it slower or looser and am I right you have given up being an elder? Anyway here would be three suggestions, 1 yes fade as slowly as you want, 2 never verbalise criticism of the org to JWs, 3 find good friends outside of the organisation.
Wishing you well on your journey and keep in touch, we would love to hear how you are doing.
