Brother Grudge:
Welcome to this board, and congratulations on displaying the courage to come here and share your intimate thoughts. I only started doing that myself several months ago and believe me, it has been the best therapy I could have hoped for.
I was, until very recently, and elder and WT conductor whose entire family was in "the truth." I am on my journey "out" right now, fading rapidly and (so far) successfully. My wife is coming with me and our grown children are rooting for us from the sidelines, even though most of them are still "in" because of marital or social ties not easily shaken. I have been pleasantly surprised that, once I made a conscientious stand, my whole family has been supportive.
Recently my wife told me, "When you started looking on the internet and running out things for me to read, I was angry with you. I thought you were going off the deep end. But everything I read made sense and expressed my own feelings and frustrations, so I kept an open mind." It worked out that way because I was very SELECTIVE about the materials I presented her with; I weeded out all the crazy stuff and wingnut philosophy and printed out the cream that rises to the top on this board. I approached it the same way she did when she helped me "learn the truth" 30 years ago, by feeding me the best parts, a little at a time.
I have come to realize that the way "out" is the same way we all got in, only in reverse. So my advice is to treat your wife with tenderness the way you'd want to be treated, continue to feed her, but feed her small bites and don't give her more than she can chew. This is what she did with me three decades ago and I bought into the JW program, despite many misgivings, because it brought us closer together.
Love is a powerful force, my brother, and Truth will out. Paul wrote that love never fails and Jesus said the truth shall set you free, and both of these principles -- if you apply them -- will work for you in this situation.
