It's sure hard to be reasonable with someone who is not reasonable! Maybe, you are right, introducing separation and discussing the ramifications may help the sitch. If that's what she wants then you are showing that you are open to what she wants. I know what it feels like to be dealing with a brick wall BUT who ever thought the Berlin Wall would ever crumble! Aside from my suggestions (cuz I am a man, fixing things ) I feel deeply for you in this sitch. Stick with it as long as you can, you'r still the hero!
