Azzork said something very important that I want to go back to. It was difficult me me to A. "get it" and once I did, B. implement it. He was talking about detaching from the outcome. I could word it that "your actions aren't contigent upon a particular outcome" or "let go of the need to control outcomes".
You have to do something because you believe it is the right thing to do without expecting a particular outcome. One example might be where you offer a backrub to your spouse but don't expect sex. Or in the case of detaching, you don't do something in the hopes of getting a response from your spouse. You have to get to the point where you really don't care if your W does or doesn't do something based on your actions. They are your actions which you are repsonsible for and her reactions are what she is responsible for. We can't post links here, but if you search "detach from outcome", you will get some really great articles. One of them relates that to "how to let go".
