The answer she gave about no OM (b/c he will never leave his family) must have hurt you. Not exactly her saying it was her choice! But that may be close to the truth as you will have for the moment. Seeing OM at work will feed her EA.
It always baffles me how the LBH feels a strong need for his WAW (who is having an A) to be able to try to trust HIM! She was the unfaithful S, and the one who has to earn YOUR trust. If you start turning it around, she will continue to feel justified. She was the one hiding the truth from you!
Don't worry about how she felt toward you not saying as much as usual. It was good that it made her feel uncomfortable.
Fwiw, you learned on the board what it means to loving her but not needing her. But She didn't. (
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
