Are you me? Seriously, reading your story took me back to about 3 years ago when I started on the same path. Pretty much the same situation as yours, except for only having one child. The best advice I can give you in regards to your wife is this: love. Show your wife that you continue to love her, and give her and your children your all to prove that you feel nothing but love for her. She will go through much mental pain as you continue on your journey, maybe even thinking about divorce as an "easy" way out, but just beat those thoughts back by showing her nothing but love. Treat her as an equal, empowering her and encouraging her to pursue her individual interests and desires. This goes contrary to the WT view of how women should be submissive to men, treating them as less than men. This will eventually help her to empower herself, which is instrumental in getting her to think for herself, and not the way the organization wants her to think.
If you want to wake her up eventually, the best thing you can do is continue to provide her questions to think about, but never providing her the answers to those questions. She has to arrive at the answers on her own. No one can ever really wake up someone else. It's the individual that wakes up themselves. But as long as she gives you her ear, tell her the questions you ask yourself, and if you feel compelled to provide her some sort of answer, phrase it in the form of a question that will linger in her mind even after you've finished talking. Facts don't stick in the human mind, especially a human mind that has been trained to reject any contradictory information. But questions do stay, and might eventually bring her enough mental discomfort (known as cognitive dissonance) that may eventually help her reason on her own.
If you really want to understand the mindset that we JW's have been indoctrinated with, read Combatting Cult Mind Control by Steve Hassan. It's a must read for anyone that has woken up, and it's a great book that helps us heal from the mental abuse we have endured all the years we were mentally in.
