suspicious jealousy
a type of jealousy in which a person fears the loss of a valued relationship to a rival even though the person’s partner has not misbehaved and there is no factual basis for this worry. Although suspicious jealousy is unfounded, it may give rise to emotions and behaviors (e.g., anger, conflict, snooping, stalking) that create the selfsame loss of a relationship that the jealous person seeks to avert. Compare reactive jealousy.
