Jealousy problem

Jealousy is one of the most common problems, it occurs already in children; jealousy can be strong even when there is absolutely no reason for it. Emotional jealousy is often based on the feeling that someone else is claiming someone’s “property”. Given the high degree of overlap of the spheres (see Fig. 2 a) and the tendency of love to be comprehensive, it becomes quite clear that this feeling easily arises between people who are in very close relations.
The intimate attitude of one of the partners to a third party not only makes him “lost” for the second partner, but also the second partner, among other things, has the feeling that some part of his own private, intimate life becomes known to this third party. By allowing the marriage partner access to his private life, the man did not intend to make it available to all other people. The relationship of a partner with a third party is perceived as a breach in the barrier that covers someone's intimate life from others.
It is important to clearly understand why situations of this kind can be perceived differently by partners.
The friendship of a husband with a third party (DR) can grow out of some kind of business relations. She may become quite important for him personally, but nevertheless still remain in his business area B or, at least, outside his soo-spring region C. Thus, the husband does not see contradictions between his family life and relations with a third party: marriage does not lose any of its areas, and the coexistence of these two connections does not lead to conflict. The wife can imagine the same situation completely differently. In her life space, the whole life of her husband is included in family relations, and special attention is paid to the areas of friendly and intimate relations. And, thus, to the wife the similar situation is represented by obvious invasion in her matrimonial sphere.
In the husband’s living space, the “third-person husband’s friendship” area does not intersect with the “matrimonial area”, which is a characteristic difference in the living space of a wife.
