The term used to describe when a father refuses to speak to his daughter because she married someone he didn't approve of is commonly known as "parental estrangement" or "family estrangement." In this specific case, it would be considered "father-daughter estrangement."
Parental estrangement occurs when there is a breakdown in communication and a significant emotional distance between a parent and their adult child, often leading to a lack of contact or severed relationships. It can be triggered by various factors, including disagreements over life choices, such as the choice of a partner for marriage, career decisions, religious beliefs, or other personal matters.
In situations of parental estrangement, the parent may choose to cut off communication or limit contact with their child as a way to express disapproval or disappointment with the child's decisions. This can be an emotionally challenging and distressing experience for both the parent and the adult child involved. Family dynamics, cultural factors, and individual personalities can all play a role in the development and resolution of such estrangements.
