hey Purr, btdt, I'm sorry for this pain, it's like a sucker punch to the gut, but this too shall pass, I promise.
I know it's hard, but her A doesnt' reflect badly on you nor your worth as a person, is about her unhappiness and her only thinking of herself and to cover her tracks (stbx also went to C with me while having a good time with then ow). They don't think ahead, they dont' think more than a week in advance, so whatever they need to do (going to C and lying to you) to keep their secret juicy A they'll do, not a thought about how hurt you'd be if you knew.
All the while she was lying she was not thinking of you (perhaps that hurts more) but that's the sad reality. As far as her turning the tables on you, pretty normal, she has to make you the bad guy to excuse her behavior, she has "perfect" reasons why it happened.
I also want to advise you to not compare yourself to the om, he is not everything you do not stand for, she didnt' choose him because he had something you didnt', he happened to be another lost person who took the easy way out by cheating on his W, someone who's morals are no where near yours. He doesn't compare to you at all.
My prayers your way)))))))))))))
