I am new to the site, just like you (actually this is my first post). I have been in the similar situation. My husband went out first (with a bang) and there was no going back for him. I was in a difficult situation, although I had phases where I was not very spiritual, then super spiritual (I once believed things could never be different), then having doubts again, after he made his decision, I went into a society defensive mode because that’s what we learn to do all our lives. We had all kinds of discussions, and got through it. Thanks to that, now I am aware of things that are going terribly wrong within the organisation, and also I have become wiser about not telling elders personal details about my marriage. I'm still going to occasional meetings, but I have open mind and I have stopped being judgemental as a result of my husband working through his issues with me. I’m not saying that’s what you should do (sounds like you have a rough time), but I just wanted to show you the other side of the story.
P.S. Your wife will have loads of witness support now, and some wives love the victim role, so whatever the situation they will always play victim, but most just need reassurance.
Hope everything works out well for you
