Hang in there buddy. And I agree with this:
For your own health and well-being, you need to stop going to the meetings. Let her go alone.
I was going through something similar not too long ago, the anxiety of everyone in my family against me, and wife (pioneer) being one of them. She has changed so much I hardly recognize her now. When she was with me on the receiving end of the my families behavior, I think her rose colored glasses with the cult came off. She saw my health (mental, emotional, and physical) being assaulted by her beloved religion.
A lot of this anxiousness comes from feeling trapped. You need to try to change your perspective so that neither of you feel trapped.
saying that she never thought she'll belong to the group of women who show up to meetings alone.
This shows me progress but still being so early on in waking up. You guys need to band together to get healthy and stable. The FOG of this org plays on everyone not wanting to be humiliated or embarrassed by being weak or in danger. When I got passed that, shit man, I felt w world better. I look at witness as pathetic, scared, sheep. I don't give 2 f-cks what they think. And I never give a sign of weakness or sadness because I am not, I am happy healthy and far more adjusted than most all of them and it shows, I am proud to be an inactive fader in their midst. So I enjoy putting that in their face (in a nice way). they can think whatever they want, I am doing me. many socialize with me often, at first I think it was weird for them, but i refuse to play by the cult road map. She needs to see this and so do you. You have to find that place.

Hang in there my friend.
