Treat your spouse like he or she is the most important person on this earth.
You chose her. She chose you. You declared, pledged and committed to spend your life with her. You decided that he was the person with which you would share the good and bad of life.
There isn’t anyone else on this earth who knows your rawest emotions, deepest desires or biggest flaws as she does. Treat him that way. Place her above all others here on this earth.
If you start to choose friends or others first, stop and remind yourself of these things.
