You're the only one you can change. But when you do, you might find your spouse changing, too. So concentrate on your own self-improvement program. Date each other. Get back in the habit of spending time together.
Prayer is a great neutralizer.
Get in the habit of turning off the television, computer, VCR and so on. In other words, put down the book you're reading and make some eye contact. Every day find a way to encourage your skunk spouse, including compliments and assurances of your love. Make yourself vulnerable to your spouse. Share your real feelings.
