Through my partner we are part of a group of friends. We recently found out that person A (male) had been sending person B (female) inappropriate messages. Person A is married and his wife was part of the friendship group. Person B cut off the friendship and explained to the rest of us why. We are all in agreement that Person A is in the wrong and we all want nothing more to do with him. But the dilemma is, do we tell his wife? She is a member of the group by extension, he was the friend first but everyone has welcomed her into the group.
A big part of me thinks that she should know. Apparently he has been sending similar messages to multiple women. But everything I know is second hand and its not down to me to tell her. But on the other hand, my husband cheated on me and others knew and they didn't tell me.
I should just stay out of it, shouldn't I?
