Why is the relationship sphere separate from the moral sphere? How do you decide what belongs in the moral sphere? Does the relationship sphere overlap with the moral sphere in other areas just not in fidelity? Why doesn't it intersect there?

Saying someone is boolean "good" or "bad" is of course complex - perhaps beyond utility. But to the extent a moral evaluation is being made of a person (unless your point is no such evaluation can or should ever be made?) I don't see how their conduct in their romantic relationships could be exempted?

I did not say it shouldnt be exempted, only that on the scale of moral judgments insofar as we are equipped to make them, cheating is and should be far down the list compared to many other acts that individually or in summary could and in many cases should make someone worse than a "good person" by the normal standards of moral judgement that most of us accept and live by.
