I think this explanation is much less likely. The quote 'it was too painful a subject to each [Darcy and Lizzy]' talks also of pain to Lizzy. Propriety, civility and respectability are the monumental concerns (part of the Austen humour, I think). Besides, Darcy is too focussed on dearest Elizabeth to worry here about his past or future relationship to Wickham. For instance:
"If you will thank me," he replied, "let it be for yourself alone. That the wish of giving happiness to you might add force to the other inducements which led me on, I shall not attempt to deny. But your family owe me nothing. Much as I respect them, I believe I thought only of you."
