My honest answer then, after your answer, is that you don't need any more proof....you don't really need to expose (but that is up to you and it may have its merits)...what you really need to do is walk away from her and the drama, consider yourself fully separated, and begin moving forward in your life as if she is not going to be part of it. I would also go to a lawyer if you haven't already. And if you belong to church, get ahold of your pastor and ask for some special one-on-one time with him, to pray for you and your family. Get into IC if you aren't already. Surround yourself with friends and family....
....but do begin moving forward as if she will not be your wife.
She may snap out of her fog, but it will likely take a long time. During that time, your heart will be breaking every moment if you are waiting for HER to decide your fate.
If you make the painful decision to take your fate back into YOUR own hands, and begin to move forward, talk to a lawyer, etc...then you will begin to start feeling a little bit better SOONER than you will if you just wait out her addiction.
And when I say begin to move forward, this is not the same as moving on. It just moves you forward by your own decision instead of remaining stuck in limbo waiting for her to decide your fate.
