Never forgetting to date your spouse is a way to keep your marriage healthy.

When you're not happy with yourself or with your spouse, your marriage will not thrive. Always being unhappy about the things going on in your life will eventually rub off on your spouse and make them feel that nothing they do can make you happy.
