" but true love goes far deeper than that. It is an unexplainable connection of the heart, one that endures triumph and tragedy, pain and suffering, obstacles and loss. It is something that is either present or missing - there is no " almost" , " in between" , " most of the time." It is the unexplainable reason that some marriages entered into after one-week courtships can last a lifetime. Its absence is why " perfect" marriages fall apart. It can't be quantified or explained in science, religion, or philosophy. It can't be advised on by friends or marriage counselors who can't take their own advice. There are no rules, no how-to books, no guaranteed methods of success. It is not defined by vows or rings or promises of tomorrow. It is simply a miracle of God, that too few are blessed to experience. "
