Once you identify and learn to speak your spouse’s primary love language, I believe that you will have discovered the key to a long-lasting, loving marriage. Love need not evaporate after the wedding, but in order to keep it alive most of us will have to put forth effort to learn a secondary love language. We cannot rely on our native tongue if our spouse does not understand it. If we want them to feel the love we are trying to communicate, we must express it in his or her primary love language.
