"Mother-in-Law Syndrome" refers to the tension or conflict that can arise between a person and their mother-in-law. This phenomenon often stems from differing values, parenting styles, or family dynamics, leading to misunderstandings and strained relationships. It can affect the spouse as they navigate their loyalty to both their partner and their parent. This syndrome is not a formal diagnosis but rather a term used to describe common issues in family relationships. Effective communication and setting boundaries can help alleviate the stress associated with these interactions, fostering healthier connections among family members.
