You are pretty much correct re: the affair comment. Would be nice for her to come back to the woman that she was before ILYBINILWY. But I should start accepting that that woman is in the past, and that I need to get ready for a new woman—the new woman from her that I hope comes through the other side, or someone else in time.
Bingo. Accept that the W you used to know is gone. Whoever she transforms into, she and God know. You don't control that. You control yourself.
