Shawn, Since it seems that the male perspective isn't working, let me give you the female perspective.
Your goals all state what you want from HER. What are you willing to do, what are you willing to change. You can't change her, but by making changes in yourself, her reaction to you will change.
I can't speak for your W, only myself, but 2 small children are very trying to care for. Since most W are primary caregivers, maybe you should listen to what she is asking from you instead of always turning it around that the problem is all hers and none of it is your fault.
I have news for you. It takes 2 people to get M, it takes 2 people to ruin a M. You need to stop focusing on your W, and her problems, and start focusing on yourself. Have you read Divorce Remedy or Divorce Busting?
Please don't run away, but if you want advice on how to change your W, you are on the wrong site. If you want to save your M, consider what everyone is saying, working on yourself, and you just might be surprised by the results.
