A person I know through family introduced me to his new girlfriend. I knew he had always said to her he was separated. In fact, he got back together with his wife (so we thought) but saw them both though both women didn't know. This gf has now found out and on top of this found that he is also seeing an ex who knows the wife and whom he had an affair with before. I was thinking today how awful for the wife that he is playing them all but she is trying to keep her marriage together thinking he has maybe only had a quick fling but in reality it's much more. Technically I could anonymously say something but not sure I want to get involved.
