In no way do I see you as the OW now. Since she broke up your M, I would wish you luck in doing the same to her. However...
I think you would be a look better off to concentrate on other non-R things for a while. Maybe just hang out with friends, concentrate on your kids, work on a hobby...
Your Ex may be back in the future or he may not, but there is absolutely nothing you can do about it right now, but keep on good terms with him. Anything else you do would be counter-productive.
It probably would be easier on you to just "write off" the R. Then if Ex does come to his senses, it will come as a pleasant surprise. Easier said than done, I know.
Posters aren't unfeeling. we do understand. We've all been there. I DBed for a very long time before giving up!
