In 1992, when I left the Watchtower organization, it was much the same as you describe ... one of the first questions is whether I believed that 'this' was God's organization. I used some evasive tactics ... and by 1995, it was the Watchtower legal department in New York that sent me a legal package, and the notice that they had determined that I had Disassociated myself. I was able to evade them a while longer, but I knew that it was over. I never said the 'wrong' phrase ... but I also failed to say the 'right' phrases, though I came close in style to what they wanted to hear ... but it was not enough for them. This is all mentioned in my exit story posted on Freeminds.org (Ex-JWs.net).
Strangely, enough, when I met with the CO, he ended up confiding in me that he did not believe "it" was God's organization, but because he was supposed to get some kind of retirement stipend in addition to some level of Social Security, he was lying low ... but he said that he did not blame me, and were he my age (41 at the time) he would leave too. Maybe you ran across him when you were a CO ... maybe not. But, it was refreshing to hear him have a moment of honesty with me ... and it was kind of validating to get him to confess to me, when I was supposed to be the problem person.
The local Elders were afraid of me for a few reasons, among which when I went to the authorities regarding a molester that they were shielding ... they begged me not to go ... but I did anyway, eventually ... and after that, they were out to find whatever they could to get me out of the organization ... and they finally succeeded ... I gave them enough along the way ... but they walked carefully until the Society told them that they would handle it, and then the local Elders became very bold toward me.
I am glad it is over ... I was able to testify years later for the victims of abuse ... and in a way, I received a level of justice. And now, I only post for a month or so each year just to stay in touch ... because I was finally able to move on to better things, a richer faith, and a meaningful life.
