As soon as I realized that a large Love Bank balance triggered the feeling of love, I went to work trying to discover what spouses could do for each other that would make the largest Love Bank deposits. I would ask couples, "What could your spouse do for you that would make you the happiest?" That very question focused on a core issue in marriage -- the issue of care. I could have asked the question, "How would you like your spouse to care for you?" As it turns out, care in marriage is doing what it takes to make each other happy.
