Hi Brian, I just want to add my "take things slow" to the chorus!
I'd also add that you have all the tools to understand how your wife will respond and to plan accordingly. You were (are) a JW and... she is your wife! :)
My advice would be to focus your precious time and energy on your family and stop throwing it away into the black hole that is the organisation as far as possible. Continue to prove the truth of the matter to yourself. It's a safe bet for me to say that you have never actually studied "the Truth". How can you prove or disprove something if you only ever consider how right it is and never consider how it may be wrong?
Lastly please remember that you have exactly as much right to happiness as your wife or anyone else on this planet and nobody, NOBODY has the right to take it away, not even the GB. Unless you let them.
