Thanks Nicole.
Despite what some others have said or think, my marriage isn't on the rocks or on the brink. It's actually been quite good except for this point of contention in recent weeks. And even then we're able to be close and communicative and intimate as always throughout this time... just not when discussing the CD topic or when she's reminded of it.
My point is only that my marriage is worth keeping and maintaining (not saving).
Your suggested approach seems to be reasonable, but I also feel that it will be useful to speak with a marriage counselor, to make sure that we are handling things in a way that is long-term healthy that allows us both to feel happy and fulfilled.
