I would confront him also, but alone, without your husband or your sister. I would tell him how it made you feel, like keepingthefaith said. And I would also tell him that was his only free pass. And if it ever happened again, tell him you will go to your sister. I don't excuse his behavior, but we all make huge mistakes. I don't know if he was drunk or not by your post, but he had been drinking. And I don't know that he needs counseling for being a horny old man. He took his shot, let it go. I know that won't be easy. Blessings.
