Eden, I am so sorry for the anguish you are experiencing. To have your wife out with you only to watch her fall prey to the cult mentality again is heartbreaking.
You have shown yourself to be a loving supportive husband through your wife's physical and mental illness. She needs to remember that time when she is giving you looks of disgust. Who else would have been there for her like you were?
I wish I had the answer for you. All I know is that everyone deserves to receive the love they give. Hugs
