@MarkWP,
I think it depends on your relationship and what works best for you both. No one person or couple is the same so a one size fits all does not always work. My opinion if it works for you and your spouse then do so. Just make sure (which I am guessing if you are both happy in your marriage) that you spouse is satisified with this handling.
Sometimes - I can see where a little time and space could help --- if you need some space to cool down and think reasonably.
I think one thing with the don't go to bed angry is it could result in having a sleepless night depending on the level of anger. However, if it is something more along the lines of we can't agree --- lets sleep on it and revisit later -- I could see time away from an impasse could help clear the mind.
