Oh Sweetie, I'm so sosrry this had to happen with pain. I'm so sorry it had to happen at all.
But I am so glad and proud of your attitude. It seems clear that there is no real relationship with this new person--I don't want to call her an OW since they got together after he left--right? That wouldn't be fair to her. None of this is fair to her because she was his rebound. It sounds like he feels stuck and since he's stuck he might as well not try to move...hence he doesn't know how he feels, no lving together, no marriage....none of that yet.
Just keep living your life as it is meant to be lived and joy will always be at your side.
