I would like to give you something to think about that is related to the theme of your last post. I think about this frequently and it often brings me at least a measure of peace. It is to do with living with uncertainty and how difficult that is to do with regard to our love relationships (or any friendship or family relationship about which we care a great deal).
Have you ever stopped to notice that we all live with all manner of uncertainty everyday and we barely even notice it, if at all? For example, we never know when we will die. This could happen every day. We live with this uncertainty daily but it is easy to live with because it is not something anyone wants to consider, so we typically do not think about this.
If we are honest, there was uncertainty in the permanence of our relationships when everything was going well. Again that uncertainty was easy to live with because we did not give it any attention.
I believe that the uncertainty of the outcome of the strife in our relationships is so unbearable because we are forced to look at it every day. This is true whether the spouse has moved out or not.
What comforts me, is reminding myself that the uncertainty was always there; it is not new demon. As such, it is a demon we know how to defeat. It is defeated by not giving it our attention. That is why GAL works so well. Distraction, intellectual occupation, physical exertion all take our focus elsewhere.
So, when it creeps back out of the basement, I just remind myself, better a devil I know...
