Have NCed for this. My lovely best friend who has been married for 5 years has just found out that her DH has been having an affair with another friend of ours for the last 2 years. The OW is not one of our closest friends but she is very much in our friendship group, she is invited to parties, nights out etc. OW was also married with DCs but unhappily. It all came out as messages between the 2 of them were discovered, they implicated them both, they started by minimising but truth has come out now. My friend's DH is now begging for forgiveness, saying he hates the other woman blah blah, anything to try and get my friend back. But luckily she being sensible and despite being devastated she is being strong and going to divorce him. However, what is really making me mad is that the OW is apparently so happy about the situation. We counted her a friend and a couple of people who have seen her say she is showing no remorse, she is basically pretty happy that she has ruined my friend's life and caused so much drama. I know MN always says don't blame the OW, and I blame both of them equally, but AIBU to want (legal!) revenge against the OW for being so heartless and awful?!
