I would not have left the house. Yes, you want to practice the rules of Divorce Busting, but you want her to SEE you practicing them. You want her to see you getting a life, hobby, doing your 180. Now she'll only talk to you on the phone and see you once in a while. If I were you, I would repectfully get back to the house. Sleep in another room and tell her that you'll respect her space.
I wouldn't have called it a "seperation". Whatever you do, don't you mention divorce. Take things slowly. Very slowly.
