A kind word or a simple email from my wife can make my whole day.
You've got a lot of work to do! Even in a healthy marriage you should be secure enough that you don't need a gesture from your W to have a great day. You are severely codependent if you need that to get by. Detach and work on yourself, try and channel the independent, strong person you were before you met your W.
I was not nearly so codependent when we were together. We operated fairly independently and I was confident in my relationship. I know I need to detach, but I can't help but feel overwhelmed by the loss of contact and presence.
