Yeah. It’s messy. I (35M) have been with my wife (32F) for 8 years, married for 5. Her sister “Amy” (29F) has always had a flirtatious personality. Think super touchy, teasing, sexy outfits around the house — it always made me a little uncomfortable, but my wife just laughed it off as “her being Amy.”

A few weeks ago, Amy stayed with us for a few days after a breakup. One night we had wine, my wife went to bed early, and Amy and I were left talking alone. It got… weird. She said something like, “If we’d met first, you’d totally be mine,” and gave me this long look. I didn’t act on it — I went to bed.

But the next day, I did tell her that I’d be lying if I said I hadn’t thought about it before. I told her nothing would ever happen and that I love my wife — but I was being honest. She didn’t say much, just nodded.

Apparently, she told my wife. My wife freaked out and said it was “totally inappropriate” and now expects me to grovel and apologize to both of them. I told her I was just being honest and drawing a line, not trying to cheat. I even told her what I said word for word.

Now she’s barely speaking to me and keeps saying, “You don’t tell someone you fantasized about their sister, even if it’s true.”

But here’s my thing: honesty matters, right? I didn’t cross the line. I stopped it before anything happened. I didn’t lie. I didn’t cheat. I set a boundary.

AITA for being honest about something uncomfortable, or should I have just kept my mouth shut?
