DH would probably say... don't argue and he won't...so we don't, though sometimes I surely try! LOL.
This is the 2nd marriage for us both. We have been married 6 wonderful years and I love him more every day. We laugh often and it's often enough at each other as much as with each other. We don't take offense because we are totally secure with each other. We say I love you often and almost always address each other by pet names. We're silly and sappy. We always kiss goodnight. We genuinely like each other. He's my best friend and I can't imagine life without him.
But the best advice I could give is to never forget that your love and your marriage is a decision, not a feeling. Getting married is a commitment. When you're not "feeling" the love (and there will be times like that!)... remember the commitment.
