Definition: Unfatherliness is a concept in psychology that describes how individuals may feel or behave towards their own children, regardless of their biological parentage. It can be seen as a form of neglect or abuse, where a child's father does not provide enough care and support to ensure his child's well-being. Some people believe that unfatherliness is caused by a lack of trust in the relationship between the child and their father, and they may feel that their own child should have been raised with them.
