According to livestrong.com, “Multiple studies have demonstrated that children fare best in households with both biological parents, but bringing up your child in a two-parent home is not always possible. A variety of circumstances result in single parenting, including: death of a parent, military service for one parent, an incarcerated father or mother, and divorce. Single parenthood affects children, but not all of the effects are negative.”
Parents can separate, but must never marry again. This is for the protection of the first family. Save the first family!
