In a lot of ways, we never stop being children. It is just as important to hear that you are loved and to feel physical touch for a marriage than it is for children. Children who have this confirmation of love and affection flourish as do marriages that have it. Marriages that do not have often look outside of the marriage to get it or are at least tempted to do so when someone gives them this type of attention.
My husband died young. When this happens to anyone, it is natural to wonder, doubt, and wish you would have done things differently. One thing that I did not have to go thru was wonder if he knew how much he was loved. I called him love, amor. Kisses everyday. No regrets.
