I have a very good friend (A) from university. I found out last night from another friend (F) (who knows us both but is close to me) that she has heard that A's DP has been cheating on her. Her DP is very good friends with my DP.
They have been together for years and he has cheated and been forgiven more than once before (although the last time that she knows of was over 5 years ago). Because of the chain of people involved it would have massive repercussions if I told her, and I think at the end of it all, she would take him back again.
However I feel awful knowing this and not telling her, and I don't know how I can be around him again knowing what I do.
WWYD? I am totally stuck.
