Yes my W would do the same, discussing R issues with other people with me. She wouldn't ask for my advice but just more as a bit of five-minute gossip.
She would have told them everything. I don't know why she felt compelled to do this; she even said to me "I don't know why I told everyone; it just came out." Yes I believe it has not helped one bit. That's her way though - act first, think and reflect later (much later!).
My goal is to definitely prove everybody wrong. They will all be thinking and telling my W - "he's a bad man", "he's not worth it", "don't bother", "once a cheater always a cheater" and so on ad nauseam.
I know I should not be intending to prove these people wrong as first priority, since my turning everything around is for me. I have that the front of my mind definitely. It would be satisfying certainly for them to get to hear about all my positive changes. But I'm satisfied with myself and that's good for the moment.
