For children in childhood (about 3- 16 years old), whether their psychological development process can be carried out according to the principle of health and order, the growth environment and family relationship are very important factors. During this period, parents' participation in education and parenting activities is the basic element of psychological integrity for children, and the constant quarrel between husband and wife is the embodiment of contradictions for children.
Children can't tell who is right and who is wrong when they see their parents quarreling. All they know is that the two closest people quarreled. They can't tell the reason for the contradiction, but they can only fall into a state of anxiety. If the core of parents' quarrel is children, then children will fall into strong self-blame; If the content of parents' quarrel is about divorce and separation, then children will fall into insecurity. These reasons will lead to all kinds of personality problems, such as inferiority, anxiety, great emotional fluctuation, extreme thinking, insecurity about the environment and self, and so on.
