Dear Abby: Cheating husband blasts wife who left him

Dear Abby: I am ashamed to admit this, but years ago I had an affair with a married man. His wife had no idea, but all of his friends knew about it. She recently left him because she met someone else, and he's not only bad-mouthing her, but also using it against her in their divorce.

Would it be wrong of me to help her by letting her know he was a big cheater? I don't want to cause her any more hurt than she's already experiencing. I no longer have any interest in him, but I think the information might help her. I genuinely feel for her.

Dear Karma: I genuinely feel for her, too. By all means volunteer the information. And when you do, do NOT do it anonymously because if you do, her almost-ex can claim the information isn't credible.
