Hell, yeah. That's an instant relationship ender. Whether or not they'll ever hook up with the same person again they've shown that they will hook up with someone besides you.

What Jim said.

Why "drunken"? Are you presuming that being drunk excuses it; therefore you shouldn't want to know, because it doesn't "mean" anything?

Iam, why a "stranger", then? It's a question. Answer it or don't.

No.

Yeah, I'd want to know. It's worse when you don't then you feel like an idiot. Plus, as stated above, instant deal breaker. No goin' back, for me, on that one.

I'd want to know but probably would already know.

No. Knowing it ruins the marriage. Not knowing can help preserve it.

I don't tell my wife the stories of my debaucherous youth, and she doesn't want to hear them. Why would we want to hear if we did something far worse?

On the other hand, can someone keep that secret for the rest of their lives? It is the sort of thing that does not get less painful with time.

So the answer has to be: In a perfect world where it would never come out, no. In the real world, tell me now, so I can jack-slap you and we can go to counseling and save the marriage.
