This is a WWYD, related to something that happened to me at the weekend. Someone I know (not a friend) is going to get married in just over a month's time.
At a drunken party, she found out that her fiance had slept with prostitutes in his 20s when he was single (I think it happened a few times rather than regularly)
For me, I'd be very tempted to at least postpone the wedding, as it would raise the question of what else had been hidden.
WWYD?
