The family environment is an emotional incubator of the individual. Depending on the affective potential of the family, certain functional or dysfunctional personality structures are created. Thus, an environment that offers physical and mental safety, comfort, emotional availability, sincere and open communication through the sharing of emotions and emotional support, contributes to the harmonious and healthy development of the future adult. In contrast, when the development environment, the incubator is hostile, insecure, violent, violating personal boundaries by violating personal space, verbally and emotionally aggressive, disrespectful to the child, authoritarian and critical, the probability of impeding a harmonious and functional development is very large, determining the development of a personality with dependency structures. These are characterized by establishing relationships of dependence and co-dependency, low self-esteem and self-confidence, submissiveness or authority, introversion or aggression, suffocation or absence. All this is transferred to the multitude of relationships that the child subsequently establishes in his life, including in the couple's relationship. This is the space where the relationships of dependent and co-dependent type appear more clearly. An dependent person loses the sense of identity (originating from a trauma of abuse), through a projective identification with the dominant parent, who develops an objective relationship with him. A co-dependent person is precisely the person who, by assuming full responsibility for the dependent person, becomes dependent on it, nourishing his false self-esteem and becoming the "hero" by undermining and dominating the other.
