Have you read DB or DR yet? I strongly suggest you do and implement the tools Michelle gives you in her books.
Sometimes doing nothing is the most powerful thing you can do.
I guarantee your wife doesn't really know what she wants right now. I suspect she wants to have her cake and eat it too. As painful as this is for you, you need to give her time and space to fully "get" what she is doing and what she risks losing.
Take care of you. Do something special for yourself today. Go for a run or lift weights, it's almost impossible to continue thinking about your sitch when you are puffing and sweating from exercise. Distract yourself.
In our culture we do want instant results, when we feel pain we pop a pill to take it away, if that doesn't work we take another one. There is no pill for this - we just have to live through it.
The most important thing I've learned through my journey is patience. Sometimes the universe sends us painful lessons to learn important truths. Maybe this is one.
Please take care of yourself.
