Certified couples and sex therapist Liat Kiro discusses the strong emotions that arise when a partner likes other women's photos online, referencing the biblical verse from Song of Songs to illustrate the intensity of jealousy. Kiro explains that jealousy, while often viewed negatively, is a natural and sometimes legitimate feeling in relationships. She notes that healthy jealousy can indicate commitment and a desire for the relationship to thrive, but warns that when jealousy takes a darker turn, it can become painful and destructive. Recognizing and understanding these feelings is important for maintaining a healthy relationship dynamic.
