Many years ago, two of my friends stood at the altar and were married before God, friends and family. Like any newlyweds, they were madly in love and saw nothing but children, happiness and loyalty as far as their loving eyes could see.

It turns out their eyes couldn't see as far as they thought. During a recent discussion with my wife, the woman confided that her husband had an affair.

Our friend had long ago acknowledged struggles in the marriage. They were often apart for days at a time on business. When they were home together, the husband's temper was sometimes short, his language coarse and his mood swings unpredictable. But his wife never suspected infidelity.
