Don't give up on her. My wife was very upset and threatened divorce when I came clean about not wanting to be a witness. Fast forward roughly 2 years later and my wife is now awake. This doesn't always happen but there are success stories.
I found when I stopped trying to deconvert her and I just let the cults tactics work for themselves she started noticing things on her own. I had planted those seeds and her natural reason ability did the rest.
