"When it comes to relationship satisfaction, you can't just ride on the big things like, 'I don't drink, I pay the bills, I don't beat you, we went to Hawaii last year,'" says Wilk. "This stuff is not really what keeps couples happy in their daily lives." What really matters is all the small stuff that adds up, such as being there for each other when one needs to vent, or noticing when he needs a hug, or making him his favorite meal just because. "It's also giving up on the idea that you have to feel in love all the time. Marriage is about trust and commitment and knowing each other," says Wilk. "That's what love is."
