Negril, I'm so sorry to read that she's still playing the replay sand box. But, you are so right to detach and go on w/your life and I do agree w/you 100%....if you do the work on yourself and let your spouse go emotionally, physically and mentally...things do get so much better.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
