Skip the mind control part and try not to let that cat out of the bag again!
Can't you guys come to an agreement of some sort such as only discussing one issue at a time? or maybe reading the bible (and not a NWT) one book at a time without commentary from either of you? Start in the NT. If you are going to email each other set some ground rules first! discuss one topic at a time, ones that bother you, and for goodness sakes she must not go to the elders with anything! ask her if you can trust her to keep this between a husband and wife? if in doubt then ask about reading a bible, say a few chapters together each night or something. You read one she reads one and end it there NO commentary allowed and bible only or if she will not agree then use their own KIT and compare the Greek to their mis-translations. I remember reading that some jw's have left the org just by reading Galations and/or Romans. We tried that but my jw couldn't keep his stupid comments to himself. I know other ubm's who also tried that with some success.
If she doubts things you found on line then buy them. They are available at Freeminds, Ebay and other places. She can and should be able to go to the kh library and compare if necessary. Not the elders manual of course, but she could bring it to an elder and ask him if it is the real deal just kidding.
I've been exactly where you are except that I was never a jw and he was a newbie jw so I fully understand the fights you are having and will have. Not pleasant at all. Keep assuring her you love her and family and for the time being let her know that you love God so much that you must find the truth behind the 'truth' because it is so important and in fact you are required to do so per the Bible (see Thess. forgot exact script a bit rusty). I say that only because I forgot where you do stand in the belief dept. Your life is bringing up many memories for me, not good ones either! I wish you a better time.
Your son staying home with you? why not? go fishing, to the park or some fun activity! Who wouldn't rather stay and have fun vs sitting in a suit completely still with your mouth shut for a few hours? Your son will not be harmed by missing a few meetings say every other week. That will be a real sore spot but you can then begin to teach some real critical thinking skills that are age appropriate. See many sites on critical thinking skills for kids. Personally after reading silentlambs, freeminds, jwd, etc... I never allowed my kids to step foot in a kh.
Will be thinking of you and hope things settle down a bit for you all. Don't forget to take care of your own well being right now. I mean-- eat, rest, try to destress. I didn't do things so I know of which I speak. Someone thought I had a terminal illness for awhile I looked like hell I was so stressed.
Things can and do get better. Hang in there. Plan a fun activity for all of you together, play a game, something, anything as a family unit.
