Is jealousy evidence of love or insecurity?

Jealousy is a familiar concept in discussions about love, especially between romantic partners. In many stories, the male lead's jealousy over the female lead's relationship with the second male lead is often what keeps audiences invested. I still remember my father’s words in response to me asking him whether he ever felt jealousy over mom’s interaction with other men, "Of course. I used to be scared that she would fall in love with another man besides me. But over time, I realized I was insecure and that I had to fix that part of myself. Your mother proved her faithfulness to me, so I needed to prove my trust in her." Although they are different emotions, romantic jealousy is often closely connected to love because both can serve complementary evolutionary purposes. Love promotes pair bonding and cooperation, while jealousy is triggered by threats to that bond. Both operate to protect the romantic relationship.     

Jealousy can be evidence of love; it can be a sign of feeling deeply in love with a partner. It may contribute to relationship satisfaction by signaling emotional commitment and encouraging partners to nurture and protect their bond. Psychologists also distinguish between reactive jealousy and suspicious jealousy. Reactive jealousy is a strong emotional response to an actual threat to the relationship, whereas suspicious jealousy stems from anxious rumination and excessive suspicion without clear evidence. But just as it can be a sign of love, it can also reveal one's own insecurity. This is where suspicious jealousy often appears. In some relationships, insecurity may lead to behaviors such as excessive reassurance-seeking or even love bombing. It often reflects a fundamental insecurity: the fear of not being enough to keep a partner satisfied. This places pressure on the partner to constantly reassure, which can lead to resentment and emotional distance. Research has shown that suspicious jealousy is associated with higher levels of neuroticism and insecure attachment, particularly attachment anxiety. These patterns may stem from childhood experiences such as abandonment, betrayal, emotional neglect, or rejection, which can create mistrust and hypervigilance in adult relationships.  

Love is the most beautiful force behind so many of our world’s greatest achievements, but, like everything else, it has its own challenges. As discussed throughout this essay, jealousy can have both healthy and unhealthy forms. Overall, my main message is that healthy jealousy should not be confused with possessiveness or narcissistic behavior because I have noticed this frequently a lot in “dark romance” books where the male lead's jealousy is portrayed as proof of love even going as far as murder. This is not something we should normalise in society. I would like to conclude with a verse from 1 Corinthians 13, “ Love is patient, love is kind. It does not envy, it does not boast, it is not proud.  It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. Love does not delight in evil but rejoices with the truth.  It always protects, always trusts, always hopes, always perseveres. Love never fails.”
