Dear Abby: When my daughter, "Trish," and her husband separated, I reached out to each of them for occasional check-ins. Trish left him after confessing to infidelity via email. He messaged me with a copy of what she'd written, which included some damning things about me -- that she was "like" me and that I am "not a good person." She never forgave me for crossing the line with a longtime friend decades ago. My husband owned his part in the situation, and we've moved past it. Apparently, she has not.

Although Trish and her husband reconciled briefly, she's moved out again and plans to divorce him. I've offered to go to counseling with her if that would help, but I don't know if she knows I know what she said about me. My son-in-law apologized when he realized what that revelation must've felt like. He shouldn't have shared her email without permission, but it can't be undone now.
