under_believer - My husband 'played the same game' as you are doing. But one day he just said 'No More!' I could see he was very, very unhappy with 'da troof'. He told me it was all rubbish and that he would never go again. I said 'fine'. But that I would still be going. When I was at meetings I missed him desperately. I decided that I'd rather die with him than live forever without him.
I faded. One day I got on the internet and discovered the real truth about 'da troof'.
It was his kindness and love all of the time, no matter what that made me choose him over the JW Cult. And it was his patience that one day had me stumbling across the real truth that he had always known.
I hope your plan works for you. But if you can be the most loving and considerate husband and father, you may well find that your family will choose you over JW land when the time comes for a decision to be made. People find it impossible to walk away from genuine love, even if they try to at first. They will always come back to you.
Don't waste too much of your life on the WTBTS. But be the best father/husband etc.
I promise you, the best man WILL win!!!!
