“In normal families a father gives support to his wife, particularly during the period surrounding birth and in the early childhood years when children make heavy demands on her. In popular parlance, he is her “burn-out” prevention. But a single mother does not have that support, and the added emotional and physical stress may result in fatigue and less parent availability to the child, increasing the risk of a relationship with the child that is emotionally more distant. The single mother generally is less able to attend to all of her child’s needs as quickly or as fully as she could if she were well taken care of by a husband. These factors tend to affect the mother’s emotional attachment to her child and in turn reduce the child’s lifelong capacity for emotional attachment for others and empathy for others. Such empathy helps restrain a person from acting against others well-being. Violent criminals obviously lack this. At the extreme, and a more common situation in America’s inner cities, the distant relationship between a mother and child can become an abusing and neglectful relationship. Under such conditions the child is at risk of becoming a psychopath.” (heritage.org) by Patrick F. Fagan, Ph.D., “The Root Cause of Violent Crime: The Breakdown of Marriage, Family, and Community
And so it seems that the father is the one that sets all of this in motion. (Or it could be the mother if she abandons her husband.) He moves on to another woman and abandons his family. This leaves the mother no choice but to go it alone and live a stressful life along with her children or look for another man to replace her straying husband which creates confusion and is very likely to cause harm to her children. Protect your first family! Do not commit adultery!
