Dan, I don't post as much here as I used to. However your experience sounds very familiar to mine. I spent 1 year doing my own research without sharing anything with others. When I told my wife that I would not go to meetings any longer she went crazy. I never even got the chance to do it one time. The next day she said she wanted a divorce and also told me she did not love me anymore. I was devistated at the time, it was truly the lowest point in my life and had many of the same feelings you have expressed on this thread. I got zero support from people at the KH, but got great support from 'worldly' people that I worked with.
Fast forward five years. It was the best thing she ever did for me. Yes, it will be hard in the short run, but in the long run you will be much happier then selling out just to keep your family in tact. You will end up resenting her and hating her in the long term if you are not true to yourself. I feel your pain, I was there, I lived it, I lost my wife, home, car, custody of children. It was a dark time while living it. However better days await you on the other side.
My only regret now, is that it didn't happen sooner.
I hope you can work it out, but if you can't, just know that it does get better.
A life away from all 'JWs' is far better for me than anything that I could dream up in my own mind that includes living with one. But that is just me.
