So my mother-in-law has been diligent in telling me what a good friendship that we have. How does she honor that friendship? She decides to go to my husbands ex-wife and tell her everything I have ever said about her!! I have bad days & sometimes it is a result of the hubbys ex & I vent,,things and feelings were expressed in confidence to a friend or so I thought. As a result this has caused some major rifts within the whole disfunctional family/friend unit,,,how do I address her and let her know that I know what she has done without causing even more turmoil.
