Oh, bro. I know this shit hurts. I was there and I wouldn't want anyone else to have to feel it. Having said that, do not spend a week by yourself. The "hamster wheel" thinking will drive you to do really stupid things. You still want to fix it. Short of a stroke, she's not gonna change her mind. What do you like to do? Do you like to read? Go to a reading at a bookstore or something, but get busy. Isolation is a downward spiral.
