With childhood exposure from my JW mother and her sister-in-law, I converted to JW in my mid-20's. From my first returning to my last meeting was 20 years. I still have a JW mother, I gained a JW wife who is still a firm believer, and I have JW in-law family. The main positive aspect of my situation is that I have no children.
Despite all the JW's in my life, I could not imagine wanting to stay ignorant for any reason at any age. While it is difficult being in a divided marriage, my marriage is strong enough to weather the problem.
As a fader, I am not shunned by my mother nor my in-law family. Even if I were, I would rather be out of that Kingdom Hall. If I had kids, I would have been quicker about getting out of the religion and letting them have a normal life. I would have accepted any JW consequences for myself to let them enjoy a cult-free life.
I have no financial penalty in my life for leaving. My start on the road to mental freedom also started me on the road to a better financial future instead of just waiting for paradise around the next corner. Staying JW was influencing my mental health negatively as I had serious unresolved issues from before converting. Freeing myself allowed me to seek proper help.
My situation above makes me biased. I am way better off in virtually all ways by being free. But I stand by my thought that all people, no matter their age or situation, deserve to learn the real truth about "the truth." I get that some are old and won't accept it, and some are in so deep or buried in it in such a complicated way that they wouldn't leave even knowing it's a lie. But anyone in such a situation should be free to decide such things for themselves.
