I know you asked earlier about getting reminders why not to bring up the OW subject. There are a number of psychological reasons for not doing so. The most important one, FOR YOU, is that anything to do with the OW (at least for now) is painful for you. Also, there is nothing you can do to stop him from being with OW.
Rather, remember to stay focused on yourself, your 180s and your GAL.
Also, as much as you are growing and are a person that only a fool would leave, remember that conversations or "things" can feel like pressure to the WAS. There may be two huge elephants in the room, and you are not ignoring them, rather you are shining lights on the positives in your life. This will go a long way to help you, and can possibly help save your M.
