Betrayed partners often experience acute emotional devastation, frequently suffering from symptoms similar to PTSD, including shock, rage, deep sadness, and severe insecurity. The betrayal shatters their trust, forcing them to question their reality, self-worth, and future. They often experience uncontrollable mood swings, emotional numbness, and, at times, obsessive, detective-like behavior.
People who have experienced infidelity report feeling betrayed, losing trust, rage, and damaged self-esteem. These are just some of the feelings a person can experience because of infidelity.
Many betrayed partners experience symptoms that mirror PTSD: intrusive thoughts, anxiety, hypervigilance, nightmares, and an inability to move past the trauma, no matter how much time has passed. The expectation that you should ``just get over it'' only adds to the frustration and isolation.
Healing from infidelity is a deeply personal journey, but research provides some timelines to guide you. With couples therapy, recovery typically takes 2-3 years, offering a 57% success rate for staying together. Without therapy, it often stretches to 3-5 years or more, with only a 20% success rate.
Infidelity trauma leads to a wide range of reactions, some immediate, others taking time to emerge and make themselves known. Anger and rage, disbelief, confusion, insecurity, anxiety, and deep sadness—these emotions often crash over the betrayed partner in waves, unpredictable and overwhelming.
However, my work with couples in the healing stages following infidelity actually shows that guilt exists in both partners. In other words, when you get into deep conversations with couples dealing with betrayal, you learn that both feel guilt/shame/blame, it is just different in nature.
7 Types Of Betrayal That Are As Hurtful As Affairs
Although not everyone experiences each stage and they can occur in any order, these stages are:
After an affair, trust in a marriage is eroded, but that doesn't always mean immediate divorce. A study conducted by the American Psychological Association showed that among married couples who experienced infidelity but then underwent couples therapy, 53% were divorced after five years.
Betrayal trauma can last until the underlying trauma has been addressed. For many people, this can take upward of a year, though the specifics can vary. Seeking treatment and therapy for trauma often speed this process up.
The 80/20 rule in relationships explains cheating as the temptation to abandon a solid partner (80% good) for someone new who seems to offer the missing 20% of needs, a pursuit often leading to regret as the new person lacks the original 80%. Infidelity often arises from focusing on flaws (the 20%) rather than appreciating the substantial good (the 80%), making an affair partner seem appealing for fulfilling that small gap, but ultimately resulting in losing the valuable foundation of the primary relationship.
Research shows that when we are betrayed, it can affect three key brain regions: Amygdala: Becomes hyperactive, increasing anxiety and alertness. Hippocampus: May struggle with memory processing due to stress hormones. Prefrontal Cortex: Shows reduced function, affecting decision-making and concentration.
Betrayal triggers our nervous system's threat response, flooding our body with stress hormones like cortisol and adrenaline. This explains why betrayal can lead to physical symptoms, including difficulty sleeping, changes in appetite, rapid heartbeat, digestive issues, and chronic tension.
Often, cheating affects individuals beyond the immediate emotional aftermath, sometimes causing a trauma response. In some cases, the psychological impact of infidelity can be so severe that the betrayed partner may experience PTSD.
Men still cheat more than women overall, but the gender gap is narrowing among younger generations. Infidelity rates peak at different age ranges for men (60-69) and women (50-59), showing age-specific patterns. Both psychological factors and relationship dynamics influence cheating behavior across all demographics.
In one camp, you have those who believe someone who truly loves their partner wouldn't cheat due to the pain and embarrassment that discovery would cause them. In the other are those who maintain that, yes, someone can cheat on a partner they love under certain circumstances.
Yet, most affairs usually end one of two ways: with divorce or a stronger current relationship. How the end plays out is up to you, how you choose to react, and how hard you want to work to stay together. Learning how to overcome grief and pain is going to be difficult, but Couples Academy can help.
The 2-2-2 relationship rule is a guideline for couples to keep their bond strong and fresh by scheduling regular, dedicated time together: a date night every two weeks, a weekend getaway every two months, and a week-long vacation every two years, which helps prioritize connection, break routine, and create lasting memories. It's a framework to ensure consistent quality time, even with busy schedules, to prevent boredom and strengthen partnership.
The 7 Deadly Sins: What Not To Do After an Affair
It will be impossible for you to trust your partner and rebuild your relationship if you aren't certain that the affair is over. If your partner is still communicating with their affair partner or still sees them, it's a big red flag telling you to walk away.
It's common to experience exhaustion, tearfulness, feeling numb, and feelings of rejection or abandonment. Increased self-doubt or thoughts of self-blame may also emerge.
Interestingly enough, some individuals who cheat also exhibit signs of dissatisfaction long before they actually stray. They may withdraw emotionally from their partners or display irritability over minor issues—a signal that something deeper is amiss within themselves rather than solely within the relationship.
Betrayal brings with it a profound sense of loss—the loss of trust, security, and the future you once envisioned. You might experience a whirlwind of emotions: anger, resentment, and sadness.
The 7-7-7 rule is a structured method for couples to regularly reconnect, involving a date night every 7 days, a weekend getaway every 7 weeks, and a kid-free vacation every 7 months.
If you've cheated, you've broken a commitment to someone else. And you've likely lied, been deceptive in your behavior, and deliberately sneaky. It should be no surprise that you've destroyed your ability to be trusted. People who know about your cheating will recognize that your trustworthiness is now limited.
