Tolerance for shortcomings.

You do not idealize a man, you do not require him to get a star from the sky. You calmly accept your loved one for who he is. But the trouble with many spouses is that they are not ready to look for common ground. Only insults and manipulation are used: “You are such / such ...”. Unwillingness to put up with the shortcomings of another speaks of the immaturity of feelings.
