Jealousy in Relationships: Causes, Signs & Solutions

The problem of jealousy in relationships is certainly not new. Ever since people began forming partnerships, it has always been a persistent issue. As evident from the tales of yore to contemporary social media squabbles, jealousy has remained constant in the life of partners through all eras. A national survey from 2024 which included more than two thousand American participants showed that 87 percent of respondents declared they had experienced jealousy in their relationships. A new study published in the 2026 edition of Societies introduced scientists to a complete new measurement system which assessed how social media use affected jealousy between individuals.

Let’s dig into where it comes from, what drives it, and whether it always has to be destructive.

Where Does Jealousy Come From?

Have you ever wondered why we become jealous at all? Well, it is not as simple as you may think. Evolutionary psychology jealousy studies indicate that this is an instinct that has evolved over time. Our ancestors that showed signs of protecting their partner had a higher chance of passing down their DNA.

Dr. David Buss, a leading researcher in this field, once said:

Jealousy evolved as a defense mechanism to protect valuable relationships from real or perceived threats.

Thus, jealousy does not simply imply possession. Rather, it is the working of the primitive alert mechanism inside our brains. The psychology behind jealousy indicates that even in cases when the danger is nothing more than a ‘liked’ picture on Instagram, our brains will still detect such danger.

Is Jealousy a Sign of Love Or Something Else?

A lot of people ask is jealousy a sign of love? The honest answer is: sometimes yes, sometimes no. A small flash of jealousy can mean you genuinely care about someone and don’t want to lose them. That part is natural and even healthy.

But here’s the catch. When healthy vs unhealthy jealousy crosses the line and becomes constant, controlling, or aggressive, it stops being about love and starts being about fear. Research from the Journal of Social and Personal Relationships found that jealousy driven by insecurity predicted lower relationship satisfaction in 67% of cases studied.

What Are the Real Causes of Jealousy in Relationships?

People experience jealousy in relationships because they feel threatened by their partner yet their partner has done nothing wrong. The causes of jealousy are rarely about what your partner did. Most of the time, they are about what is happening inside you.

Here are the most common root causes:

Jealousy and self esteem

Jealousy and insecurity

When you don’t feel good enough, you assume your partner will find someone better. A study in the self and Identity journal found that people with low self-worth experienced jealousy 2.3 times more than others.

Jealousy attachment theory

Psychologist John Bowlby’s attachment theory explains this well. People with anxious attachment styles are especially prone to jealousy because they constantly fear rejection and abandonment. They need more reassurance and can read threats where none exist.

Comparison culture

Social media makes it worse, and it clearly shows why do people get jealous in relationships. Seeing your partner interact with attractive people online triggers jealousy faster than real-life interactions.

How Does Jealousy Affect Relationships Over Time?

Understanding how jealousy affects relationships is crucial because the damage often happens slowly. It does not blow up a relationship overnight. Instead, it chips away at trust, communication, and emotional safety piece by piece.

Can jealousy destroy a relationship? Absolutely. Research published in 2025 in Computers in Human Behavior confirmed that the link between social media jealousy and intimate partner violence is bidirectional meaning jealousy fuels aggression, and aggression fuels more jealousy, creating a dangerous cycle.

Here’s how it typically unfolds:

First, small accusations start. “Why did you talk to them so long?
Then, monitoring behavior begins. Checking messages, tracking locations
Next, emotional withdrawal sets in. One or both partners stop sharing openly
Finally, resentment builds until the relationship either explodes or quietly dies

Is Jealousy Normal in Relationships And Can You Actually Manage It?

Yes. Every single person who has ever loved someone has felt it at some point. You are not broken for feeling jealous. You are human.

But “normal” does not mean “unmanageable.” Here are practical ways to handle it:

Name it honestly – Say “I felt jealous when…” instead of lashing out. Naming the emotion takes away half its power.
Trace it to the root – Ask yourself am I reacting to what happened today, or to something from my past?
Talk before you assume – Most jealous thoughts are stories your brain invents. Check them against reality by having a calm conversation.
Build your own confidence – Jealousy shrinks when self-esteem grows. Invest in your own goals, friendships, and identity outside the relationship.
Seek professional support – If jealousy is consuming your daily life, a therapist trained in attachment or cognitive behavioral approaches can help you rewire those patterns.

As therapist Esther Perel puts it:

The quality of your relationships is determined by the quality of your relationship with yourself.

What Does Allah Teach About Jealousy?

According to Islamic teachings, envy is tackled through the deepening of faith and acceptance of the wisdom of Allah in granting his bounties. The connections of every individual and his/her destiny are unique in their own way, and thus making comparisons will simply cause internal disturbance. This problem is best solved through practicing gratefulness, patience, and sincerity in one’s heart.

And give them preference over themselves, even though they were in need of that themselves. (Qur’an 59:9)

Conclusion

Insecurities in love have been there since times immemorial and they are part of human nature, resulting from our biological makeup, upbringing, and even our environment in which we now exist. But recognizing the source of insecurities is key to ensuring that they do not take control of your relationship. In whatever form, whether mild or overwhelming, jealousy in relationships is not the problem itself but rather how one deals with it that makes all the difference.
