throw it in a waste paper basket, and label it with a sticky that says "things I will no longer waste my time with going forward" and leave it in clear site.
Once she sees that you are "giving up" and no longer going against the separation/divorce that's when things will change.
You currently don't agree with her on any of this, you're counter-intuitive 180 is to agree with her, this is hopeless, it will never work, I'm done wasting my time on this.
This will make her curious, currently she expects you to do everything & anything to stop what's happening.
Do the unexpected, throw it out. (Recover it at a later point from the trash when she's not looking and store the book at work where she can't see it).
And then start getting a life, stop spending so much time at home, friday get all fancied up and go out, even if it's a drive to the next state or staying at a motel room for 1 night or better yet, don't fake it, go out with buddies and come home very late: shower, shave, haircut, new outfit, shoes, cologne, etc. and go out and if she asks where you're going, you tell her that what you do no longer concerns her anymore and turn your back on her and walk away.
Become the WAS, do what she's doing, don't give her attention anymore, stop asking her questions or talking to her, limit your contact, go dark, get a life, go to the gym, start tanning, start going out regularly and appear to be moving on.
What you're currently doing isn't working, stop doing what doesn't work, start doing what does work.
