As long as we're talking hypotheticals, adultery does not necessarily entail deceit: it simply means one member of a married pair is having sex with someone who is not their married partner. Adulterous relations, therefore, could include ones where one married partner knows about the other's extramarital daliances.

If you want to restrict the discussion to situations where the partner having extramarital relations is deceiving the other, and further stipulate that deceit is unacceptable, then of course it is--but only on the stipulations you've made. So who's setting the conditions that are stalling the conversation?
As far as deceit in intimate relations being _a priori_ bad, though, I have two words: surprise party. -- Curtiss
