I'm sometimes a little bothered by how little I actually worry about WAW and what she is doing or thinking. I still care, and I think her coping mechanisms are going to lead her into a bad place down the road, but its so much out of my hands that I feel like putting energy into it is only useful if I'm thinking about how I want to move or act.
I wouldn't be bothered about this. After all, there's no point in worrying about what can't be helped -- you're quite right in recognizing that her choices are out of your hands. I believe that this is what the detachment process is all about. You can hope that your W will stop making poor decisions for herself, but you also have to get to a point where you can extricate your emotions from this hope.
I think as we detach, we get to a point where we realize that it is our duty to truly look after ourselves, our needs, and our desires, rather than those of our WAS. It is a healthy place to be.
