"Anyway, I know I am supposed to take focus off of her and GAL but I just haven't found a way to do so yet."
What's holding you back, exactly?
"Also, the going dark thing is going to be extremely difficult as she expects us to remain friends and communicate throughout this separation."
Are you content with that? Are you willing to move from husband to friend?
And honestly, the going dark is for YOU. It isn't to "get her to realize" anything. It's to give you space you need to be able to detach. It sounds like you are sitting around at home with your free time waiting for her to come around to talk to you.
If you want any chance at resolving this, the first step is to focus on you. Not on her.
