JAG, I remember you. Wow, things have really turned around for you.
I like your decision except for #4. If you're going to a counselor, go to an entirely new one. Your IC has a biased view of the sitch.
I would wait before talking about this w her. She might be acting out of emotion.
I am going to sound sexist and no offense to anyone, but I think men who've been left have a much higher chance to get their W's back bc women are driven by emotion. When men leave, they usually find OW right away and have no interest in R (although many of them pursue cake-eating.)
Listen to your heart and be patient as you come to a decision.
