She is, in a real sense, out of her mind. At least in terms of, she is not the same person who married me.
Or. more likely, she is not the same person you THOUGHT you married. I must admit, my ex didn't "suddenly change" when his MLC hit. Looking back, I can see the red flags that were present even in the beginning, but that I chose to ignore. A narcissist can seem fine when they're wooing you and happy with you because you make them look good or fit their current idea of what they want. You might not notice the uneveness in the relationship while it seems fulfilling enough. I thought I was being a good, flexible spouse by accommodating him but in retrospect I see how much more I gave than he did.
