Yep -- I agree. And I wasn't even addressing the "right" or "wrong" of it (personally, I'm opposed to it, unless there is infidelity involved, you're clearly moving on towards D, and you let your spouse know, as a courtesy) -- just saying that it WORKS, and that efficacy has to be factored in along with the "does it make it more or less complicated" question.

Lots of powerful forces are complicated.
