The aim of this paper was to examine the relationship between jealousy, attachment, and the use of manipulation tactics in romantic relationships and to examine gender differences in emotional, cognitive, and behavioral jealousy, anxious and avoidant attachment, and the use of manipulation tactics. The online study was conducted on a sample of 535 people aged 18 to 35 who have been in a romantic relationship for at least six months. The questionnaires used were Modified Inventory of Experiences in Close Relationships, Modified Manipulation Tactics Scale and Multidimensional Jealousy Scale. It was found that women are more inclined to use direct tactics of manipulation, while men and women equally use indirect tactics of coercion and indirect humoring tactics. It was also found that women show higher levels of emotional jealousy, while men have a higher score on the dimension of avoidance. Positive correlations of all three manipulation tactics with the dimension of anxious attachment were found, while indirect tactics of coercion and humoring were positively correlated with the dimension of avoidant attachment, and direct tactics were negatively correlated with this dimension. Then, indirect tactics of coercion and humoring were positively correlated to all three dimensions of jealousy, and direct tactics were positively correlated to emotional and behavioral jealousy. Furthermore, the dimension of anxious attachment was positively correlated to all dimensions of jealousy, while the dimension of avoidant attachment was positively correlated to cognitive and behavioral jealousy. Hierarchical regression analysis explained a total of 37.2 % of the variance of indirect coercion tactics, 12.8 % of the variance of direct tactics, and 17.8 % of the variance of indirect humoring tactics. The best predictor of indirect tactics of coercion and humoring was behavioral jealousy and anxious attachment, while the best predictor of direct tactics was emotional jealousy.
