I am by no means a vet in this regard in anyway, (I have currently just entered R with my W), but I must say I feel that GAL is imperative to any BD scenario, and 180 as well. By detaching and utilizing the time to find oneself and contemplate how to grow as an individual will inevitably strengthen you as a person and enable you to be better prepared for whatever life may bring. In this manner, your W may notice these changes and second guess her decision to D. Utilize the time to grow as a person and become the best you can be. I'm rooting for you, much love.
