For example, if alcoholism plays a role in the behavior of the morbidly jealous individual, treatment of their addiction can positively affect their progress in trying to change their jealous nature. While psychotherapy can be an effective method of treating morbidly jealous persons, it is not sufficient when the nature of their illness is more serious. It is not possible to say that there is one form of treatment that is superior over all those that are currently available. Even though this may be true, cognitive behavioral therapy is the treatment that has proven to be most effective.Medical

Confirmatory behaviors
When suspicions of the partners fidelity arise, they quickly become all that is thought about. Certain behaviors, such as interrogation of the partner, repeated telephone calls to work and surprise visits, stalking behavior, setting up recording devices in the home or work, or hiring a private detective to follow the partner, are all common in trying to determine if there is truly infidelity or if it is just perceived. Individuals that are jealous may take drastic measures, such as searching the partners clothing and belongings, look through diaries and other communication methods (email, text messaging), or examining bed sheets, undergarments and even genitalia for evidence of sexual activity.
Pathological jealousy, also known as morbid jealousy, Othello syndrome or delusional jealousy, is a psychological disorder in which a person is preoccupied with the thought that their spouse or sexual partner is being unfaithful without having any real proof, along with socially unacceptable or abnormal behaviour related to these thoughts. The most common cited forms of psychopathology in morbid jealousy are delusions and obsessions. It is considered a subtype of delusional disorder.Overvaluing an idea, which is defined as “an acceptable, comprehensible idea pursued by the patient beyond the bounds of reason. The idea is not resisted and, although it is not a delusion, the patient characteristically attaches utmost importance to investigating and maintaining the partner’s fidelity at great personal disadvantage and to the distress of the partner”. Overvalued ideas are characterized by being existent in the individuals own thoughts, being egosyntonic; meaning that the ideas project the behaviors, values, and feelings that are aligned with the desires and aims of the individuals ego, or consistent with the individuals ideal self-image, the ideas are also amenable to reason but are not resisted. Definition
This disorder occurs when a person typically makes repeated accusations that their spouse or sexual partner is being unfaithful, based on insignificant, minimal, or no evidence, often citing seemingly normal or everyday events or material to back up their claims. Unlike other delusional disorders, people who suffer from this disorder have a strong association with stalking, cyberstalking, sabotage, or even violence.
