More than the "I love you", more than just feelings and hearts beating genuinely for the other person, more than always wanting to be with/around the other person, more than wanting to see, hear and speak with the other person.... Love is not the only thing that hold a marriage. Love is good, believed to be the most important reason but it is still not enough to sustain a marriage. There is trust, transparency,honesty, kindness, willingness to accept the truth without being defensive,hardworking, goal oriented, emotional intelligence, etc.
