I will agree that that is an extreme case and obviously there is a limit at which point people just aren't compatible. If you can't sleep in a room with a pile of laundry in the corner and your wife still has the box from every pizza she has ever eaten then the marriage may be doomed but assuming that the issue is more minor, I think that lowering your expectations to balance your level of marital happiness against your ideal level of home cleanliness is a good thing to consider. Maybe I am biased because I don't give a fuck about neatness but to me having a placid marriage is a hell of a lot more important than whether or not the vacuuming is done regularly. I don't think cheating is a good comparison because cheating breaks the fundamental basis of the relationship contract where dirty laundry is at worst a minor inconvenience (with the possible exception of some extreme cases).
