Morbid jealousy, also known as 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.〔 ''Some symptoms of pathological jealousy include: * Accusing partner of looking or giving attention to other people. * Questioning of the partner's behavior. * Interrogation of phone calls, including wrong numbers or accidental phone calls, and all other forms of communication. * Going through the partner’s belongings. * Always asking where the partner is and whom they are with. * Isolating partner from their family and friends. * Not letting the partner have personal interests or hobbies outside the house. * Controlling the partner's social circle. * Claiming the partner is having an affair when they withdraw or tries to escape abuse. * Accusing the partner of holding affairs when the marriage's sexual activity stops because of the abuse. * Suffering from the lack of reassurance. * Lack of trust. * Verbal and/or physical violence towards the partner, the individual whom is considered to be the rival, or both. * Blaming the partner and establishing an excuse for jealous behavior. * Denying the jealous behavior unless cornered. * Threatening to harm others or themselves. 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 individual’s own thoughts, being egosyntonic; meaning that the ideas project the behaviors, values, and feelings that are aligned with the desires and aims of the individual’s ego, or consistent with the individual’s ideal self-image, the ideas are also amenable to reason but are not resisted." ix〔http://www.freethoughtlebanon.net/2012/10/pathological-jealousy-its-symptoms-and-definition/〕 ==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. It can be found in the context of schizophrenia and delusional disorder, such as bipolar disorder, but is also associated with alcoholism and sexual dysfunction and has been reported after neurological illness. The name "Othello Syndrome" comes from the character in Shakespeare's play ''Othello'', who murders his wife as a result of a false belief that she has been unfaithful. Recently some workers have asserted that Othello was deceived rather than deluded about Desdemona’s alleged infidelity and thus did not have ‘the Othello Syndrome’.〔Crichton, P.
