Think play, not romance.
Forget flowers, dinner and candles, and instead play a video game, have a water-gun battle or play in a photo booth (or with Photobooth if you have a Mac!).
Accept that you're both going to make mistakes, and if the mistake was not intentionally hurtful, let it go. Adjust your expectations and align them with reality (dirty towels on the floor, pre-menstrual hormone insanity), not fantasy (a pristine house, a perpetually perky disposition).
Reinvigorate the Old.
Life's grind sometimes whittles away the parts of us that are carefree, inspired, focused or fun. One of the best things you can do for your spouse is to defend the parts of them that you married them for. And that doesn't mean saying "You used to be so..." It means reminding them that they ARE those things; they're not gone, even on their most beaten down days.
Discover the New.
Embark on unplanned adventures. Often.
