As a anxiety specialist, I initially used the term “retroactivity jealousy” in OCD circles. Since then I have come across more people who treat it and see it as a manifestation of OCD. This inspired me to take a closer look at the research.
What is jealousy of return?
“Jealousy of return” is a term that originated in, rather than in, clinical psychology Social media. That anxiety related to past romantic partner relationships and sex meetings
People who struggle with retroactive jealousy often experience intrusive and painful thoughts about their current ex-partner. In addition to jealousy, emotions are also involved fear/ anxiety angersadness and shame. They may experience mental images of romantic or sexual encounters from their partner’s past in a way that feels intrusive.
In response to this anxiety, they may:
- Repeatedly ask your partner for details about past relationships.
- Search for information about ex on the Internet (“cyber research“).
- Mentally replay or compare past relationships.
Although these behaviors are an attempt to reduce anxiety and seek reassurance that their relationship is special, they often have the opposite effect – the intensity of emotional pain and anxiety.
It is important that the current relationship is not under any threat from the previous relationship. A person dealing with retroactive jealousy is usually not worried that their partner is in danger of cheating. Instead, a study by Frampton and Fox (2018) showed that anxiety about real risk unfaithful and more about the idealized expectation of a unique special relationship. When this ideal is threatened, the partner feels threatened – even in the absence of any significant problems in the relationship.
Adding to the complexity, individuals experiencing jealousy are often aware that their reactions are harmful to themselves, their partners, and their relationships (Blaney & Burgess, 2023). They realize that their repeated questioning of their partner about past relationships, attempts at reassurance, and anger and insecurity about their partner and their partner’s past are likely to damage their relationship. But understanding alone isn’t enough to resist—at least not for long.
An online brand was born
Unlike other psychological terms, jealousy is not derived from scientific or clinical experience. Instead, it was created and promoted through online forums. self help groups, social media and popular press articles.
Researchers are trying to study a phenomenon that was accepted in popular culture before it was scientifically determined. As Osorio (2025) notes, retroactive jealousy has already been discussed in articles and online forums as a legitimate mental health disorder—despite limited empirical support. Even the Cleveland Clinic has a website dedicated to it.
The Internet can not only name and spread this experience, but also contribute to why people are now in tune with it. Before social media, information about a partner’s past relationships was usually limited. People were custodians of their romantic history and could choose what they shared or not. Today, a digital footprint can provide extensive and sometimes painful access to a partner’s romantic past. As one client said, because of his compulsive internet research, he now knew more about his ex than his partner.
Where does OCD fit in?
OCD is characterized by intrusive, unwanted thoughts (obsessions) and repetitive behaviors or mental actions (compulsions) performed to reduce anxiety. A common compulsion is to seek certainty—through inspection, questioning, or research.
There are clear similarities here. Retroactive jealousy also involves reassurance seeking: repeated questioning of the partner, psychological testing, and attempts to gain reassurance—behaviors that resemble OCD compulsions. As in OCD, these efforts tend to backfire rather than reduce anxiety and increase anxiety, perpetuating a cycle of anxiety.
Prevention also plays a role. People may avoid places, things, or situations related to their partner’s past. For example, one may avoid eating at restaurants where they know their partner has dined with their ex in the past in order to engage in fun activities related to their partner’s romantic past.
Given these overlaps, it’s understandable why some consider retroactive jealousy to be OCD or even relational OCD, a subtype of OCD that involves persistent doubts about one’s relationship and which I have written about in the past.
But the similarities may be more superficial than they appear. The link between retroactive jealousy and OCD appears to have been established online independently of any scientific consensus.
While I can understand why people associate retroactive jealousy with OCD because of the common behavior mentioned above, it does not have an important functional overlap with OCD: the result or consequence of fear. People with retroactive jealousy are not afraid of something bad happening in the future, as we might see in OCD obsessions. Rather, OCD people map relationships into established OCD frameworks with fears that they may not be in the “right relationship,” which they realize too late and will cause severe pain to themselves and/or others in the future.
What the research suggests
Emerging research paints a more complex picture of rebound jealousy.
Across multiple studies, Osorio (2025) examined whether retroactive jealousy is related to OCD, OCD attitudes, or even borderline personality disorder (BPD) characterized by unstable and intense relationships. The findings were surprising: retroactive jealousy met none of these conditions.
In fact, the research suggests something even more fundamental: retroactive jealousy may not represent a single psychological construct at all.
Instead, it may be better understood as a label applied to a range of experiences, including jealousy, insecurity, and difficulty tolerating a partner’s past. In other words, the internet may have given a catchy name to a range of emotional struggles, but that doesn’t necessarily make it a specific disorder.
Implications for treatment
If retroactive jealousy is not a form of OCD, this has important implications for treatment.
Exposure and response prevention (ERP), the gold standard treatment for OCD, is not appropriate in these cases. The “response prevention” part of the ERP can be useful in helping people understand that certain behaviors may be contributing to their anxiety, in teaching them to resist the urge to engage in Internet research about past partners, and to avoid reassurance behaviors. However, the effect may not be as effective as ERP for OCD. Instead, Osorio (2025) recommends programs that directly target dysfunctional thought patterns. I found acceptance and commitment therapy (ACT), newer cognitive behavior therapy that teaches people how to recognize and release unhelpful thought patterns that get in the way of connecting with otherwise loving relationships is helpful.
Final thoughts
Rebound jealousy refers to anxiety about a partner’s romantic or sexual past—even when the past poses no present-day threat. Despite its limited scientific support, it quickly gained traction on the internet and is often described as a mental disorder and a subtype of OCD.
Current research shows that there is no clear evidence that retroactive jealousy is part of OCD, or even that it constitutes a mental health condition. Instead, it may reflect a familiar human experience enhanced by modern access to information and shaped by cultural expectations about relationships. That being said, someone can have OCD and retroactive jealousy, like some people I’ve worked with.
For those interested in a deeper dive, a thesis by Michael Osorio (2025) Provides a comprehensive historical and empirical survey of the topic. A student of Richard McNally, Ph.D., a prominent Harvard psychologist known for his research on anxiety conditions, Osorio’s thesis provides valuable context and includes new research not yet published in peer-reviewed journals at this writing.
As research continues, one thing remains clear: not every distressing experience fits into a single diagnostic category—and with so much content online, it can be difficult to parse accepted mental health diagnoses from common terms born and bred online.
