Friend, soon she will no longer be your wife and you can officially leave her to take care of herself (not that she didn't always have that responsibility, mind you).
My AXH said the same thing after I left him, he went to rehab and the started drinking again. At one point, he asked me by email if I had ever considered WHY he had to drink so heavily when we were married when he hadn't before and when he was able to go to rehab and quit as soon as I was out of his life.
It's quacking. That's all it is. It's also not taking responsibility for your own actions which would be worrisome for a person who's supposedly recovering... But it's a process.
I don't think you need to worry about how she describes reality. You know the truth.
