I hope you've had a relatively good Thanksgiving considering the circumstances you're in right now.
My suggestion is to go FULL-ON LRT on your W by going pitch black. Don't initate anything or talk with W after she moves out. She needs to truly experience the loss of you as her H and best friend. She needs to hit rock bottom to realize the magnitude of her choice(s).
One poster did. Now he and his W have successfully reconciled. This poster's name is Thornton. You might want to read up on his thread in Newcomers, that is if it is still around.
