| Adapted from an online discussion. Dear Carolyn: I have reason to believe my husband’s sister’s husband is cheating on her. I don’t know for certain, but I’m pretty sure. I’m unclear on who I should tell. Do I confront my brother-in-law? Tell my sister-in-law? Tell my husband? The problem with telling my husband is he will surely fly off the handle and confront his sister’s husband, possibly violently. — Anonymous Answer this week’s reader question Here's your chance to channel your inner Carolyn Hax and respond to a reader question. |
