Those were precisely the same emotions Mr Scully and I went through when we were in the process of leaving the JW belief system.
The clincher for us was reading in the Aid Book™ and the Insight™ volumes under the definition of the word LIE.
It said words to the effect that "it is not necessary to tell the truth to individuals who are not entitled to it." Think about that for a minute. Who are they saying is "not entitled to" truthful information? The average JW thinks about opposers who want to incriminate them or the Organization™. But clearly, it could also refer to the GB withholding honesty from average JWs. We had noticed, multiple times in fact, where the Publications™ conflicted with one another (flip flops like who among those who were killed at Sodom and Gomorrah would be Resurrected™; or wholesale rejection of higher education, then allowing for it, then rejecting it again; saying Armageddon™ was Just Around the Corner™ for exactly how many decades now?).This plus so many other things made it abundantly clear that JWs were not purveyors of The Truth™, they never were and they never would be.
We were humble with our eldest, who was old enough to understand the ramifications of leaving. We told him that we had been fooled by people who didn't have our best interests at heart, and that we were going to start making our own decisions instead of allowing the JWs to influence us. It was a great feeling to let go, and get out as a family.
