Have part of your life that is separate from your spouse. Don't feel like you have to be together every moment.

Don't yell. On the other hand, understand that tempers may flare at times.

Don't criticize your spouse in front of others.

Don't be afraid to apologize. Perhaps often. As close as you are, you are still two individuals with two separate ways of thinking and doing.

Watch Moulin Rouge together. Take time each day to reflect on what a glorious thing love is.

Be honest.

Go on walks together.

Compromise.

Appreciate the little things in life and about each other. And when the little things do get to you, step back and think of how lucky you are to have this beautiful thing called love.
