I am in the same boat. I love my wife very much, but she has not learned to separate US from the Governing Body.
As crazy as it may sound - I still go to the meetings because I love her and I think its the closest to what a christian should be doing.
For years I do my part by being kind and affectionate as much as I can so she can at least "feel" I love her. I try very hard not to make a comment nor a facial reaction to anything that sounds dumb or stupid.She knows my hatred for the GB.
From time to time she ask me my opinion and I try to be as "professional" as I can.
last week in listening to the August JW broadcast something that was said on there made me burst out with "come-on-man"!! and she said "what"? I explained what was wrong with some statements and she got upset and stormed out. I went after her and she said leave me alone just "leave me alone".
two days went by without a word from her- so I text her and told her in so many words- how in the world can you get mad at me and treat our relationship this way based on some men we dont know and will never meet. I married you for YOU and not because of the kingdom hall but because she was a spiritual person.
That seem to calm her down and slowly we got back to normal. SO if you love her do your part to make her feel that despite being an apostate your love is not based on the organization but her. That may help a little.
