I can give you some insight into the W after an A. This actually just happened this past weekend. I have been struggling a lot w/ feeling insecure w/ myself knowing that he had gone to OW for whatever it was that she could/would give H instead of trying a bit harder to get me to work on R and let me know exactly what was lacking, however, that's old news/dead issue now.
I finally backslid a bit in the way I approached the EA on Friday evening, however, it turned out ok in the end. His cell phone had rang and he said it was "work." I've been thinking all along that his "friend" was a woman at work so I later made a snide comment (backsliding) about his cell phone. I then proceeded to tell him that I knew she still called. He said yeah, so & so and so & so call me (from work), but I don't work w/ my "friend." Then I'm left to wonder where in the heck he met someone and ended up having an EA with her, but I've moved beyond that.
He told me then & there that his "friend" "has been taken care of." I've come to the realization that I need to accept that and move on. Your W may not have enough info about your A that she needs in order to "move past it."
I have to agree w/ GEL and say C is the best thing you can do right now if you can get W to agree to it. But you may also need to have a convo w/ her about the A specifically and find out if she has enough info about it to deal with it and move on.
