One morning in early January 2005, Wendy Plump's neighbour came over to tell her that her husband was having an affair. The news hit her with an almost audible click. It was not a shock. Actually, it explained quite a lot. What she was not prepared for however was the revelation that he had an eight-month-old son living within a mile of their family home.Monogamy is one of the most important vows we make in our marriages. Yet it is a rare spouse who does not face some level of temptation in their married life.
