A useful book for you to read is "Combating Cult Mind Control" by Steve Hassan.
Your wife is stuck in a cult and the book describes that people have two different personalities when in a cult. A cult personality and an authentic personality.
The book helps loved ones focus on the authentic personality to help them move on slowly and eventually see they are in a cult that they need to escape. Not everyone can help their loved ones but there is some very good advice in the book.
If you really love your wife I would recommend you read this book and try taking some of the advice in it.
If it's not working then the best thing to do is divorce. But if you love her, try first.
