My other half is as bad as I am - so not really a good thing. I've got "play" money set aside and as long as I stay within my "budget" he doesn't have reason to gripe - well, unless he ends up tripping over them.
When that happens, I tell him to watch where he is going and pick up his feet!
And then I make him a carrot cake, or Italian creme cake, or cinnamon rolls, or one of his other favorites. It's rather easy when you are married to someone who has the way to their heart through their stomach.
