I don't really feel like I can talk to her openly about how I feel about the org. Sometimes she will complain about the Elders or say that she doesn't see any point in going to meetings. However, when she says those things she is looking for me to set her straight and tell her what she needs to do. If I agreed with her then I'd be letting her down. According to her thinking I'm supposed to be the "more spiritual one" as the head of the household.
Been there. My wife tested me in so many different ways and treated me like shit every time I disappointed her with my lack of zeal for the cult. While it was rough for a while (and things are still very much up in the air in a lot of ways) it turns out that just being honest with her was the best thing and I wish I'd done it earlier. Your wife is probably scared. She knows something is going on and since you're not telling her she could very well be inventing stories in her head like mine was and that's likely making her very insecure and unsettled about your marriage and her future. That tension isn't going to result in anything good - even if you're not open with her about your issues with the cult, I think trying something to reassure her of the strength of the marriage (buy her flowers, take her to a nice place she's been wanting to try, take an afternoon off work to spend time with her, whatever) and your commitment to it would be a good idea. If you can make her feel comfortable about things without bringing the cult into it, you'll only be making your relationship stronger for the difficulties it's likely to face in the near future.
Just my $.02, take it or leave it. You obviously know your wife better than I do and you know your situation better than I, but hopefully this is a little helpful. At the very least know you're not alone in this and whatever happens you'll get through and have a great cult-free future.
