I coined the term "Little Bo-Peep" approach to refer to the theory that if you simply leave them (the cheating pair) alone, the affair will die its own natural death, without any outside intervention, and that it's in fact BEST to just leave it alone, and work on yourself. It is pretty much the conventional wisdom on this site.
You know, "leave them alone, and they'll come home, wagging their tails behind you."
In any event, I think I said in one of my posts above that I wasn't referring at all to you with this, nor do I think Mark is (although he can speak for himself).
I don't think it's far off-topic, though, because this approach pretty much is the antithesis of the "confront/expose" that you and I were debating.
