Snooping is inevitable but always more painful when you learn more about the relationship that is not yours. I am sorry you have had such pain but think you have really gotten to a good place to be able to move on.

I have vowed not to be the one to file for the divorce but don't really know if I can keep that promise. My H seems content to live as roommates and expects me to find my own happiness - which I am working on but it doesn't happen overnight. H has already found his happiness.
