Yeah, I’ve long since stopped asking, “When is the happy date?”, when someone tells me of their “fiancee of 20 years.”
Of course, I think my own kid and her cohabitant refer to each other as engaged. Not sure they have any intention of getting married at any specific time. Pretty sure they gave each other power of atty, named each other as beneficiaries, etc.
In contrast, my wife and I were married well under a year after our first date!
