If it's any solace to you, remember that I was in the same boat as you in terms of driving my wife away with neglect, compulsive gaming, not responsive, etc. (mine had the EA aspect in addition). I experienced the same guilt and fear you did, wondering if I could "fix" things to prevent the separation. From what you've written, your W is in the same boat as my (and most other WAS) are in.
She still knows she wants out, she is already emotionally checked out, she is hurt.
The loving thing is to agree with her and give her what she wants. You don't know what will happen if you do that. She might reconsider separation when she sees you FINALLY listened to her, she might separate and then begin to heal and find herself back to you when she sees you aren't in a tug of war with her anymore and have shaped up, she might separate and never look back. No guarantees, but if you ever want to listen to her, now is the time.
Let her begin to heal, and continue working on yourself. I stood in your shoes of fear right before separation. I still don't know how my sitch will turn out in the end. But, do the brave thing, quiet the fear in you, and listen to her.
