there are some profound loving caring and very wise words of advice here.
Well here is mine. Dont wreck your marriage in the process.
I/we are in the same boat. I never mention anything of the 't' as she has a come back (according to the party-line). I have found even the gentlest most considered inquiries result in SOL.
The price I pay for myfading years has been no sex (there I said it) no touching, no simple gentle day to day conversation fuck all general conversation, no sharing of interests. and frequent outbursts of why I should get e new car ( this is the sisters influence loud and clear) and that she hates the house SIA ( sisters influence again).
So be very a where that so many sisters see only the perceived opinion of themselves by other jw as important over and above their spouse so they are adverse to being seen as different and there is nothing more different than challenging the party line, questioning the same or outright leaving. In leaving their social intercourse is lost for all the reasons we have read on this site down the years.
Take this to heart if you and your wife still have anything left of an intimate relationship then back off on the wt challenges. Tell yourself I will NOT raise any wt "issues" after any mid day so your afternoons and evening meal times and perhaps bed (!) time will be pleasant for ye both. You are going through hell and she will be going through the mangle by some of the 'self-righteous' class and even the 'dragon-class' because you are not being seen as her little suit, tie, approved shoes, shaven, haircut, follower the wt require.
Buy peace with regular flowers, take in a concert, be a manly man with your personal appearance, tidiness and suffer her to watch whatever tv she may wish to watch and find in your own life the great value in your hobbies and friends and meditations'.
You might collect some computer 'favourites' eg. the elder lying to the ARC, real stinkers of headlines, etc and keep them for the rainy day when she will raises the wt issue. You can show her what finished the wt for you what has been going on behind her back. Expect disbelief and some acceptance or not.
My heart bleeds for all in your situation.
Peace; Live long and prosper.
