Chastity is a psychological personality trait, made up of many factors and manifested as a limited ability or total absence of an emotional response to troubles and social experiences. Mental honesty means not only reducing the reaction to the events of the lives of those around you, but also the inability to manifest your own experiences quite openly and in the correct form.
The hardness of the soul is largely determined by the style of education and the traumas and other life events. So, boys are intentionally vaccinated with low emotional responsiveness, explaining this with masculinity and stereotypical views on the concept of a real man. Experienced emotional distress associated with relationships can reduce the sensitivity of a person due to the protective mechanisms of the psyche. Those who often fall into the situation of betrayal, and the relationship evolved from the point of view of self-interest, it is difficult to openly manifest tender aspects only because of the existing memory of the fact that in past similar conditions this led to serious emotional trauma that may not be taking place until now.
Toughness in relationships is increasingly explained precisely by the increased vulnerability of the inner world, which can only be saved by completely eliminating interaction at deep levels. The more a person shows that he is invulnerable and indifferent enough, the higher the chances that he will not be approached emotionally, and he himself will not give anyone the opportunity to approach in such a way as to cause injury again. In many situations, when a large amount of time passes, the hardness may be replaced by an abnormal level of emotional response, and supersensitivity.
