Partner had an EA with my BIL. She denied any wrongdoing. My sister called saying she had found messages on her husbands phone between my wife and him. Nothing sexual. Overly close, they both spoke about their marriages and issues within the marriage, reference to private calls, unkind things said about their own and eachothers spouses by both of them.
They are both furious that their innocent friendship has been questioned.
What do we do? My sister is really emotional. My partner is furious but her and BIL have checked in with eachother to see how they each doing (🚩🚩???)
