Mitterrand wasn't in a triad. Actually, I seem to recall his wife didn't even meet his girlfriend until he was either dying or dead, I can't remember which (and at that point his daughter from the girlfriend was already an adult). The wife knew, as did many people, but it was, for one thing, a vee, not a triad, and for another, it was one of those "I'll look the other way and tolerate it" examples previously mentioned.
