The article discusses about the relationship between romantic love and psychosis. Argues that romantic love is often the cause of psychotic decompensation. That phenomenon may be associated with the structure of personality and pattern of attachment of people with experience of psychosis. Anthropological studies show how the phase of falling in love through recreating the mother-child relationship can become threatening for people with psychotic personality structure. Researchers affiliated with the Bowbly theory emphasize the risk of "self-expansion" in the early stages of romantic love. For people who have good experience on early childhood care, such experience is appealing and exciting, people surviving psychotic fear of the actual loss of boundaries, may react defenses in the form of psychotic delusions. The article includes excerpts from the history of the person with experience of developing psychosis. It shows how important is to study the causes of illness, understanding of the disease in the context of the patient's life. Therapists should try to understand the message of the delusions and hallucinations of the patient. Patients who react with psychosis on romantic love could have difficulties with a closer relationship (including therapeutic relationship).
