Nothing can be built sustainably without tolerance as long as the limits or boundaries established at the beginning of the relationship by the two partners are not exceeded. The roots of the emotional problems that appear in married life must be sought in the past, in each person childhood, in the relationship they had with each parent, and here the case history is very rich. All parental patterns will later develop in the child's adult personality. Because everything is a vicious circle and perpetuates itself, parents may not be entirely to blame.
