My parents had this kind of relationship, Alma Rosa. (By the way Alma Rosa is a beautiful name.) I remember talking to Monsignor Wade about their relationship and he told me that they had created a relationship they were comfortable with. I would never be comfortable with that kind of relationship and worked hard at making sure my marriage was kinder and more loving than I saw with my parents. I think "happily ever after" does last. It just last differently for each couple who makes it work.
One of my favorite sayings about marriage goes something like this, "The sign of a good marriage is that everything is debatable and challenged. Nothing is turned into law or policy. The rules, if any, are known only to the two players, who seek no pubic trophies."
