Welcome to the forum Dorie!
To answer your question, I began my exodus when they changed the meaning of one of their prophecies - AFTER IT FAILED! Their prediction was that the Soviet Union would overthrow the US in a struggle for power and then the great tribulation would begin. They based this on a prophecy in the Book of Daniel about the King of the North and King of the South. Well, when the Soviet Union collapsed, they did a quick backpeddle in a study article - no apology really just more like, oh, we were mistaken about that .... moving on. I was shocked. But it seems I may have been the only one because as I looked around the kingdumb hall, everyone else seemed to take it on the chin (or maybe they were daydreaming). I wondered to myself, if they were wrong about THIS what else could they be wrong about?
It didn't take long to find out. A couple of years later they relaxed their prohibition on colleg education (see my profile on that) then it was the 'this generation will by no means pass away until all these things occur'. The GENERATION was supposed to be the generation that saw the events of 1914. That meant that the end was very close (yeah, right). The current teaching is some convoluted mess I can't even articulate - but regardless, that was the last straw for me.
You see, JW religion demands a lot from its adherants. As you stated, some parents do not emphasize education because the end is supposed to be so close. But what happens when your nephew grows up and cannot find employement because of lack of formal education? I had to look at the price I was paying to be a part of this religion. If what they were saying wasn't true, and obviously it isn't, then I had to take my life back and begin to make a future for myself and my family. That plus the fact that I was just so damned tired of walking a tightrope for people who didn't give a rats ass about me personally. The burden was so heavy - I knew it couldn't be from God.
I wish you all the best dorie. You are truly a caring individual to spend your time trying to find a way to help your family. Don't give up hope, there are new posters here EVERYDAY who just up and left the religion or are trying to find out the truth about the cult da troof and make some sort of exit.
