“…Jealousy in romantic relationships is present in all societies and cultures and it involves a set of complex cognitive, emotional, physiological, and behavioral responses determined by a perceived threat to an intimate relationship by a rival, regardless of whether that threat is real or not (Elphinston, Feeney, Noller, Connor, & Fitzgerald, 2013;Gouveia, Silveira, Santos, Souza, & Belo, 2015;Pavela, Banai, & Šimic, 2014;Ramos, Yazawa, & Salazar, 1994). The diversity of such responses can be observed through the set of feelings associated with jealousy, such as anger, fear, sadness, excessive distrust, and may be accompanied by aggressive behavior (Buss, 2000;Doğan, 2016;Elphinston et al, 2013;Wigman, Graham-Kevan & Archer, 2008). Research shows that jealousy is a heterogeneous condition ranging from normal to pathological, with different degrees and levels of persistence manifested over time (Marazziti et al, 2010;Ramos, et al, 1994).…”
