Welcome and my heart goes out to yo hang in there I know how you feel comparing yourself to Truman. My exit felt just like the ending. Sadly my husband is still in we have 2 young children, so I like so many others here understand you circumstance. Some here have had their mates leave with them so you have a fund of knowlrdge here and on other sites.
Along with Black Sheeps suggestion I also suggest reading
Crisis of Conscience by Ray Franz
Combatting Cult Mind Control by Steve Hassan
Understanding Mind Control Among Jehovah's Witnesses e-book by Randall Watters
