What Is Retroactive Jealousy (a.k.a Rebecca Syndrome)?
Retroactive jealousy is when a person has an unhealthy interest in a partner’s past relationships. It can feel as though they are threatened by their partner’s previous experiences, even if there is no actual threat present. This jealousy can feel intense, anxiety-provoking, and intrusive. It can also become distressing, disruptive, and detrimental to relationships.1
To help you better understand Rebecca Syndrome, the following sections look at the origins of the term, as well as how it differs from normal jealousy and its potential causes.
Rebecca Syndrome Meaning and Impact
You may have heard the term “Rebecca Syndrome” used to describe retroactive jealousy. The term was inspired by a novel written in 1938 by Daphne Du Maurier called Rebecca.2The novel describes a woman being haunted by the memory of her husband’s first wife, Rebecca, feeling as though she will never be enough compared to her. It details the psychological impact that feeling consumed by thoughts of a previous partner can have.
Normal Curiosity vs. Obsessional Thinking
As mentioned earlier, it’s not uncommon to be curious about your partner’s past. Healthy curiosity often comes from wanting to understand things better, including romantic connections.
Jealousy, however, happens when you believe that someone or something else is a threat. For instance, someone else flirting with your partner, or your partner giving their attention to someone else, could make someone feel less important. This type of jealousy is often short-lived, occurs in the moment, and can come and go without causing harm to your relationship.
Retroactive jealousy, on the other hand, means becoming obsessively fixated on a partner’s past. It causes distress to the person having the thoughts and can seriously harm their relationship.
On the side of the person experiencing the jealousy, a cycle of regret, compulsive actions, and self-sabotage may become the norm. For their partner, the impact of jealous behaviors can erode trust and cause feelings of torment over how they cannot change their past.
It can help to understand the causes of retroactive jealousy in teens to fully grasp how treatment can work. The following section covers potential causative factors.
Causes of Retroactive Jealousy in Teens
If your teen gets distressed over their partner’s past or seems to obsess over their partner’s exes, they may be experiencing retroactive jealousy. It’s important to be kind and empathic when approaching the subject with them, because the causes of retroactive jealousy can stem from self-esteem issues or attachment challenges. For example, some of the causes of retroactive jealousy in teens can include:1,3,4
- Insecurity
- Low self-esteem
- Insecure attachment styles
- Fear of betrayal
- Rejection sensitivity
- History of trauma or abuse
- Past experiences of infidelity
- Health challenges associated with hormonal fluctuations
- Chronic medical conditions
- Brain injury
The Role of Insecure Attachment in Jealousy
Attachments are the blueprints formed in early childhood as a result of our earliest relationships with our primary caregivers.5 When an infant’s emotional needs are consistently met with love and accuracy, they may develop a secure attachment style. This style typically gives them a healthy foundation for future relationships.
Yet, if a child’s needs are not perceived as being consistently met, they may develop an insecure attachment style, which may result in a less healthy template for future relationships. For example, they may believe that partners cannot be trusted. In this sense, attachment trauma leading to jealousy issues may be understood through the lens of an inherent mistrust of others.
Social Media and Rebecca Syndrome
There’s a lot to be said about social media’s role in teen jealousy. The ease with which social media can be checked could make it easier for some people to start obsessive behaviors.
To put it simply, with one tap on a phone screen, many teenagers can access photos or posts from their partner’s history. They might also constantly check social media to see if their partner is “liking” posts or photos by their ex, or vice versa. As a result, seeing images of a partner with exes or observing ongoing interactions could add fuel to the fire of jealousy.
Underlying Mental Health Conditions
It’s useful to note that sometimes, retroactive jealousy can be a symptom of an underlying mental health condition, for example:1,4
Bipolar disorder- Depression
- Psychosis
- Personality disorders
- Anxiety
- Obesssive-compulsive disorder (OCD)
Conditions such as these can fuel insecurity, potentially leading someone to believe that their partner’s exes will naturally be superior to them. Therefore, they may become hypervigilant towards threats to their happiness – even if these threats are in the past.
Yet, although some people with retroactive jealousy may have an undiagnosed mental health condition, it’s important to remember that this is not the case for everyone.
Signs of Jealousy-Related Relationship Stress in Teens
With this in mind, the following are some common red flags for retroactive jealousy or teen relationship insecurity signs:1,3,4,6
Obsessively questioning their partner about past relationships- Searching for their partner’s exes, pictures from previous relationships, or other details, on the internet or social media
- Following their partner’s previous romantic connections on social media
- Going through their partner’s phone or internet history
- Accusing their partner of cheating
- Asking for reassurance about their current relationship
- Comparing themselves to their partner’s ex
- Feeling anxious when previous partners are brought up in conversation
- Feeling as though the past is threatening their relationship
- Thoughts and fears about their relationship interfering with daily life
- Feeling frustrated
If you recognize some of these signs in your teen, they may be experiencing retroactive jealousy. Of course, your teen may actively try to keep these signs hidden from you, which might require you to be especially observant of their online behaviors.
Before we delve into ways to support your teen, let’s take a closer look at the impact of jealousy on a teen’s mental health.
How Jealousy Affects Teen Mental Health
For example, the mental health effects of obsessive jealousy can bring feelings such as anger, hostility, inadequacy, and bitterness. In addition, obsessional thoughts, low self-esteem, low self-worth, anxiety, depression, or even feelings of paranoia may develop.
Again, while some of these feelings are natural when they are transient, they can become problematic when they are a constant presence. Teens may become critical, lose trust in people, feel suspicious of their partner, or find themselves snapping more through frustration.7-9
It’s clear that retroactive jealousy can affect mental health, but it may also manifest physically. For instance, teens may experience aches, heart palpitations from anxiety, weight changes, or sleep problems.7
Teens experiencing Rebecca Syndrome may also withdraw from friendships or leave hobbies by the wayside so that they can focus solely on their relationship.8 Further, the fixation on their partner’s past may leave them with little room for academic work. As such, their grades may start to decline.
As can be seen, the effects of retroactive jealousy can be far-reaching. They can impact a teen’s mental and physical health, as well as their social life, relationships, and academic work.
The following sections explore treatment options for emotional regulation for jealousy-driven anxiety in teenagers.
Treatment Options for Retroactive Jealousy in Teens
If jealousy is interfering with your child’s life, professional support can make a big difference. A therapist can help teens identify what lies beneath the jealousy and find ways to address and cope with their feelings. Some effective therapeutic approaches for retroactive jealousy are detailed below.
CBT for Jealousy and Obsessive Thinking
Cognitive behavioral therapy (CBT) can help change the ways teens think and behave. It allows them to recognize unhelpful thoughts and behaviors, challenge them, and replace them with healthier options. A key technique in CBT is called “exposure and response prevention” (ERP).
ERP allows a person to confront their jealousy triggers without performing their go-to compulsions, such as asking for reassurance or looking things up online. This is done in a safe environment and in a gradual way so that they can learn to control their reactions.6
DBT for Intrusive Thoughts in Adolescents
Dialectical behavior therapy (DBT) teaches a person how to tolerate distress and regulate their emotions in a healthy way. By doing so, DBT can help teens manage overwhelming anxiety and jealousy.10
Therapy for Insecure Attachment Patterns
Attachment-based therapy may help adolescents when retroactive jealousy stems from insecure attachment. Attachment-based therapy allows teens to build secure attachments, improve communication, and learn how to regulate their emotions in a safe and supportive environment.11
ACT for Retroactive Jealousy in Teenagers
Acceptance and commitment therapy (ACT) doesn’t try to stop intrusive thoughts from popping into the mind. Instead, it helps teens to accept their thoughts without judgment or reaction. For instance, if a thought such as My partner is going to leave me for their ex comes to mind, a teen can learn to acknowledge that they are having an intrusive thought, rather than acting on the fear it brings. This can help them detach from distressing emotions that arise from the initial thought.12
Inpatient Care for Severe Jealousy in Teens
For cases of severe retroactive jealousy, when there are risk-taking behaviors or severe mental health challenges such as complex trauma, inpatient care may be considered. Residential recovery programs provide a safe and supportive space with 24/7 care from professionals to allow your teen to focus fully on their recovery.
Coping Strategies and Family Support
There are things that teens and their families can do to support themselves outside of therapy. Some coping strategies for controlling obsessive thoughts in teens could include:
- Acknowledging that your partner has experienced relationships before, and reminding yourself that this is normal and the past is in the past
- Focusing on the facts: Your partner has chosen to be with you, not with their ex-partner.
- Journaling about your thoughts and feelings so that they can move out of your mind and onto a page
- Practicing mindfulness to help you let go of distressing, intrusive thoughts. For instance, developing a mindfulness practice, such as those suggested on our mindfulness exercises page, may help to ease the intensity of feelings
- Taking a break from social media can remove the urge to dive into a partner’s feed, looking for information about their past relationships
- Picking up an old hobby or seeing other friends can be a healthy shift, especially if relational obsessions are persistent
- Educating yourself on retroactive jealousy and Rebecca Syndrome. Knowledge is power, and you have the strength to recover.
Family Support for Teens With Obsessive Jealousy
If your teen seems consumed by jealousy, please know that they haven’t chosen to feel this way. You can help them heal by learning about retroactive jealousy, what drives it, and showing them that you understand.
For instance, be there for them to talk about their feelings and thoughts. You could also encourage them to pursue other interests and activities they used to enjoy if their relationship obsessions seem to be taking over their life.
Further, if they are struggling with jealousy, you could approach the topic of professional help with them, such as seeking out a therapist who specializes in relationship jealousy. Be patient, compassionate, and show your teen that you are there to support them.
