Children all over live under fathers who are poor role models or express no care to love their children. Any child (and mother) wound find it traumatic, even more so when the child has autism.
Everybody’s first impression of adulthood comes from the parents. For girls, the mother must show them how to be a woman. For boys, father must show them how to be a man. In both cases, the father, being the usual household leader, stands as the whole house’s role model. You don’t have to agree, but in most circumstances, that is just how it goes.
