Parental estrangement refers to when children cut ties with their parents. It has become more common in modern society. Experts have found that many parental estrangements are due to unresolved disagreements rather than violence or neglect. Family therapy can help repair damaged parent-child relationships caused by estrangement. Estrangements often result from conflicts over new romantic relationships after divorce or from a child's accusations about lack of parental support or criticism, leaving heartbroken parents unable to communicate with their children.
