hang in there brotherdan, things always get worse before they get better.
maybe subconsciuolsy she reacted so strong, because deep down she may know (feel) youre right.
Just consider, JW hang their whole life on the future, if they have family, their future is to be with family in the paradise. Anything that endangers this hope is like a catastrophy for them. The worst that can happen to a JW according to their perspective, is that a loving family member (spouse(child) leaves the truth and will therefore die in A.
Its still real for her, so she will put up a strong defense in order to keep her view, that she cherished for so many years. because, be honest, after knocking down the WTS, often there is nothing left, you have to learn to enjoy life now !! This is a big change, it does not come overnight.
I would suggest, instead of destroying the building of the WTS, try to built up a life for her around the presence, by being there for her, show her your love and attention. Built up real spirituality, help her to think for herself. Time and again, uncover fallacies in WTS reasoning.
Every situation is different, but thats the way I try to get to my wife, and sometimes I see progress, but expect also fallbacks. Patinece is needed, and often you may have to just swallow certain nonsense you hear at the meeting of with other JW.
Wish you the very best, and dont forget this place here, mayn share similar expereinces, and it helps!!
