Glad to hear it worked out well, for you. Even if DBing hasn't saved your M right now, your efforts have certainly allowed you to become the person you are and opens the door to a great future.
Maybe one day I will be comfortable being in the same room as my stbx and even sit at a banquet table with her at some future, family event, laughing and chatting like old, great friends.
Right now, I don't have any desire to do so. But... who knows what the future will bring.
Did you get the "closure" you wanted? Or did you instead get a sense of hope?
