The difference between romantic love and companionable love is that romance comes and goes but friendship lasts forever. One can have both, but if the lines of communication shuts down ,then so does the marriage. I asked my parents what made your marriage last so long. They said we never forgot we were a couple. We were a couple before you kids came a long and never lost sight of that fact. We set aside time for eachother no matter how short the time every day. They kept their love alive by working at it and never took eachother for granted. It can be done.
