Get your conversation beyond coordinating schedules and talking about the kids. Take time to talk about ideas and dreams. Give back rubs. Another day you'll be on the receiving end. Find something daily to share a laugh about.
Life is complete with laughter.
Do what your spouse wants before being asked. Anticipate your spouse's needs and jump right in to help. Put his or her needs before your own comfort. You don't have to solve problems, just be an active listener. Turn off the TV, put down the newspaper, and give your spouse your full attention.
