Hi there and welcome!
I won't give you any advice, because frankly, I don't believe there is any to give. Each situation is different and some are worse than others. Your wife, just as we were, is like a junkie. No amount of hinting, nudging etc. will change her mind. Like a junkie, something has to click within her in order for her to reflect on her position. If she's not ready for that yet, you won't be able to make her be ready ... push too hard or too soon, she'll hit the pipe harder. The KH & JW is her 'comfort' her 'be all-end all'.
Its soooo like being a drug addict. One will get help only when one is ready.
You keep on doing what you are doing. Read, check into things, etc.
