Hey Paul, work on realizing and accepting that this M is over. You may at some point have another with her or someone else but the one you were in is over.
I had sort of a mantra when thoughts about what he was doing or not doing would crop up, The marriage is over, I need to live my live accordingly and keep moving forward.
I would also ask myself, What would I be doing differently if the D was official?

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
