Discovering infidelity in a relationship can be profoundly devastating. The emotional fallout is not just a fleeting moment of pain; for many it can spiral into a persistent state of psychological distress. Although not a medical diagnosis, this condition is known as Post Infidelity Stress Disorder (PISD). It can be like your whole world is turned upside down in a minute—everything you thought you could rely on suddenly seems false, all that you knew to be true, a lie. If you have experienced infidelity, it can be helpful to learn about how other people cope with and move through this often devastating experience.

You might be asking yourself, what is PISD? Does everyone who experiences infidelity experience post infidelity stress disorder? And what are the symptoms of PISD? In this blog we’ll discuss the effects of infidelity on one’s psyche, why infidelity impacts us like it does, how you can begin to recover from post infidelity stress disorder, and how to decide what to do about your relationship.

 

Understanding Post Infidelity Stress Disorder (PISD)

PISD occurs after one learns about a partner’s infidelity, leading to symptoms that mirror those of Post Traumatic Stress Disorder (PTSD). Individuals may experience severe psychological distress, including intrusive thoughts, hyper-vigilance, and a profound sense of betrayal that can disrupt their daily functioning and sense of security. The discovery of a partner’s affair often shatters the foundational trust that the relationship was built upon, leading to intense emotional turmoil and uncertainty about the future. PISD can affect our ability to form a trusting bond with a partner, resulting in difficulty starting and deepening new relationships. For some, this distrust can become a major theme of their relationships even many years after the inciting incident.

It is important to note that not everyone will experience PISD. A healthy and proactive approach to dealing with trauma can lessen the blow of infidelity. 

How PISD Can Affect You

The effects of PISD can be all-encompassing. Emotionally, it can manifest as sadness, anger, confusion, and a sense of worthlessness. These feelings are often accompanied by physical symptoms such as insomnia, changes in appetite, or physical numbness. Socially, PISD may cause withdrawal from friendships and family, as the individual struggles with whom to trust and how much to share about their personal ordeal. The individual may find themselves expecting to be betrayed or hurt, and this may play out in relationships in a number of ways, most of which are not healthy.

Why It Happens

PISD stems from the traumatic impact of betrayal. Infidelity undermines the basic assumptions that partners hold about their relationship and each other. For many, a partner’s affair contradicts their view of their partner as loyal and the relationship as a source of security and happiness. Many basic beliefs about self, partner, and relationships in general may be suddenly called into question. This profound dissonance between belief and reality is what triggers the stress response typical of PISD. It can take a lot of time and reflection to integrate the new reality in a healthy way, and there’s no guarantee that without the proper guidance this will ever happen.

 

The Similarities to PTSD

Just like PTSD, PISD involves episodes of re-experiencing the traumatic event (the discovery of infidelity), avoidance of reminders associated with the affair, negative changes in thoughts and mood related to the relationship, and heightened states of arousal (such as being ‘on edge’). These symptoms are not only distressing but can be debilitating, affecting one’s ability to function normally in daily life.

 

 

Five Things You Can Do to Relieve Symptoms of PISD

• • Reconnect with Your Support Network: Lean on friends and family who you trust can provide emotional support and validation during this challenging time.

• • Journal Your Thoughts and Feelings: Writing down your thoughts can be a therapeutic way to handle overwhelming emotions and clarify your feelings about the relationship and what you want for the future. You may find important insights about yourself, your relationship, and your relationship to relationship.

 

Deciding What Steps to Take Regarding Your Relationship

Deciding whether to stay in or leave a relationship after infidelity is a deeply personal decision and one that comes with many considerations:

• • Assess Willingness to Change: Recovery from infidelity involves both partners. It’s crucial to evaluate whether your partner acknowledges the wrongdoing and is willing to make amends.

• • Consider Couple’s Therapy: A professional specializing in couple’s therapy can facilitate a more constructive dialogue about the infidelity and help both partners understand and address underlying issues in the relationship.

• • Evaluate the Relationship’s Foundation: Reflect on the relationship’s strengths and weaknesses. A strong foundation can sometimes be rebuilt with mutual effort and commitment.

• Listen to Your Intuition: Ultimately, listening to your own needs and feelings is crucial. Trusting your intuition about what’s right for you is essential in making a decision that aligns with your best interests. If you’re having trouble finding your own direction and intuition after being “blended” in a relationship for so long, Hypnotherapy can help you reestablish your individuality again.

• Letting Go: If your relationship is beyond repair, it may be time to let go. A divorce or break-up is always a painful process, but there are steps you can take to make it easier.

 

Frequently Asked Questions About Post Infidelity Stress Disorder (PISD)

 

What is PISD Disorder?

PISD (Post Infidelity Stress Disorder) refers to a condition experienced after discovering a partner’s infidelity. While not an official medical diagnosis, it mirrors symptoms of Post-Traumatic Stress Disorder (PTSD), such as intrusive thoughts, hyper-vigilance, and emotional distress. PISD often arises from the betrayal of trust and security foundational to a relationship.

Why Am I Experiencing Hyper-Vigilance After Infidelity?

Hyper-vigilance is a trauma response, and it is your brain’s way of attempting to protect itself from possible danger. For example—if you survived a tiger attack, it makes sense for your brain to become hyper-aware of tigers. Just like you can develop hyper-vigilance after a car accident, mugging, or other traumatic event, infidelity (and your reaction to discovering it) can actually rewire your brain to become constantly “on-guard” against another traumatic event.

What are the symptoms of PISD?

Common symptoms of PISD include:

• Emotional distress, such as sadness, anger, or confusion
• Physical symptoms like insomnia, appetite changes, or numbness
• Intrusive thoughts and rumination about the affair
• Hyper-vigilance and difficulty trusting others
• Avoidance of reminders of the betrayal
• Negative changes in mood or perception of relationships

 

How does PISD compare to PTSD?

PISD and PTSD share similarities, including re-experiencing traumatic events, heightened emotional responses, and avoidance behaviors. However, PISD is specifically triggered by the emotional trauma of infidelity and its impact on one’s sense of trust and safety.

 

What causes PISD?

PISD stems from the emotional trauma of infidelity. Betrayal contradicts core beliefs about one’s partner and relationship, leading to a stress response. This emotional dissonance can disrupt personal stability, creating symptoms similar to those experienced after other traumatic events.

How can infidelity affect trust in future relationships?

Infidelity often creates long-lasting trust issues. Many individuals with PISD struggle to trust others, fearing betrayal in new relationships. Without addressing these issues, distrust can become a recurring theme, impacting the ability to form deep and secure connections.

Can therapy help with PISD?

Yes, therapy can be highly beneficial. A therapist trained in trauma or relationship counseling can help you process feelings, rebuild self-esteem, and navigate decisions about your relationship. Couples therapy may also assist in rebuilding trust if you choose to continue the relationship.

What are some coping strategies for managing PISD?

• Seek supportive therapy to process emotions and rebuild trust.
• Establish boundaries in your relationship to create space for healing.
• Develop techniques to manage intrusive thoughts and rumination.
• Prioritize self-care activities like exercise and mindfulness practices.
• Reconnect with trusted friends and family for emotional support.
• Journal your thoughts to clarify feelings and gain insight into your healing process.

 

How do I decide whether to stay in or leave the relationship?

Deciding whether to stay or leave is a deeply personal decision. Consider these steps:

• Assess your partner’s willingness to change and rebuild trust.
• Seek couples therapy to address underlying relationship issues.
• Evaluate the strengths and weaknesses of the relationship.
• Trust your intuition about what’s best for you.
• If necessary, take steps to let go and move forward independently.

 

Is recovery from PISD possible?

Yes, recovery is possible with intentional effort and support. Healing involves addressing emotional wounds, rebuilding self-confidence, and fostering healthy relationships. While the journey may be challenging, it can lead to personal growth and a fulfilling future.
