MM, thanks for the compliment. It is an uphill battle. A battle that you don't know if you can win, but you have to do what you think you should do. Continuing on is about you, just as her decision is about her.
My H and I could be in a similar battle. My H isn't near as ready as your H, but I feel he struggles with the same battle in his heart and mind that I see in your W. As where your W is looking at the getting back together part, my H struggles with even opening himself up to wanting to get back together. He says he was so unhappy for so long and escaping was his secret way to fix it. It's hard to dislodge those thoughts from the WAS's mind. I hope you find your peace and her too. I hope that's together. It's worth me noting that I think your approach to this whole thing will give you peace regardless of the outcome.
