Jealousy and morbid jealousy are the phenomena commonly encountered by psychiatrists. Its significance extends beyond the clinical characteristics and treatment to forensic aspects as well. This jealousy results in behaviors designed to prevent partner infidelity and to retain their romantic partners. These retention behaviors can be both nonviolent and violent and differ in males and females. Morbid jealousy is a symptom with different psychopathological presentations resulting in distinct psychiatric diagnosis and treatment. Obsessive jealousy in particular needs special consideration as it goes unrecognized or more often be mistaken for delusional jealousy. In contrast to delusional jealousy which expresses itself with the strong degree of conviction of partner's infidelity, obsessive jealousy presents as recurring, unpleasant, undesired, unwanted, and irrational thoughts of their partner's infidelity. In obsessive jealousy, the individual suffers from a possibility of unfaithfulness which can be sexual and emotional with resultant monitoring behaviors.
