Divorce laws have evolved over centuries from only allowing divorce for causes like adultery to broader acceptance and regulation of divorce through state laws. Currently about half of first marriages in the US end in divorce. Divorce affects both parents and children, with common parental issues including emotional distress, unhealthy coping habits, and social isolation. Children of divorce often experience lower self-esteem, difficulty with relationships, feelings of responsibility for the divorce, and behavioral or academic problems. Effective co-parenting with open communication helps children adjust after a divorce.
