People have affairs due to complex factors like unmet emotional or physical needs, feeling disconnected, seeking validation for low self-esteem, boredom, revenge, or simply due to opportunity, often stemming from a mix of relationship problems (poor communication, neglect) and individual issues (past trauma, addiction, personal growth desires). Infidelity isn't always about a failing primary relationship; sometimes it's about seeking a lost part of oneself or fulfilling needs the partner can't provide, even in seemingly happy couples.
For example, many said they cheated due to anger, lack of love, low commitment, esteem, situation, and neglect. Importantly, the reasons why they cheated not only impacted their affairs but their primary relationship as well. There are a lot of reasons why people cheat on their romantic partner.
Affairs often start subtly, beginning with emotional disconnection, unmet needs (like feeling unseen or unappreciated), and blurred boundaries, frequently blossoming from friendships, especially at work, through shared frustrations, lunches, or social media, evolving from mental/emotional intimacy to secrecy and physical betrayal as individuals seek validation, novelty, or a lost sense of self, rather than a happy person usually seeking an affair.
The best stance for therapists to take is encouraging clients to explore all of their feelings about the affair and their marriage or partnership and to help them hold all of these intense emotions, though not necessarily at once.
The psychology behind why people cheat in relaionships.
Hunger for Emotional Intimacy: Many people cheat not for physical reasons but because they feel emotionally unfulfilled in their relationships. They seek external validation, attention, or intimacy that is lacking in their relationship.
Cheating on a partner doesn't always mean love is gone.
Many who cheat still feel love for their partner and guilt for the infidelity. Cheating can stem from emotional distance, insecurity, or the fear of missing out. Addiction, stress, or past trauma can drive infidelity without negating love.
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.
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.
The 5-5-5 rule for couples is a conflict resolution tool where each partner gets 5 minutes to speak uninterrupted about their perspective, followed by 5 minutes of joint problem-solving, creating a structured 15-minute conversation to foster understanding, empathy, and calmer resolution by preventing escalation and promoting active listening, say NBC News, this Facebook post, and this Instagram reel. It helps slow down arguments, allowing for thoughtful communication instead of defensiveness, and builds stronger bonds by showing mutual respect for feelings and opinions.
Right now, learning that it takes an average of 2 to 5 years to get over the pain of infidelity may seem impossible. How could you ever get over such a betrayal? Yes, recovering from such a blow is going to take a long time, but there are actions, such as therapy, that can facilitate recovery and save your marriage.
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.
While many factors contribute, many experts point to poor communication (especially criticism, contempt, defensiveness, and stonewalling) and a breakdown in emotional connection/trust, often stemming from dishonesty or disrespect, as the #1 things that destroy marriages, eroding intimacy and making partners feel unheard and unloved over time. Infidelity, financial stress, and shifting priorities (like putting family/in-laws above spouse) are also major contributors that feed these core issues.
There are several types of personalities that have been found to be more prone to cheating, including narcissists, psychopaths, and those with an avoidant attachment style.
Surprisingly, these full-blown affairs almost never start at a bar or club. Instead, they usually begin in much more wholesome environments: The workplace. The workplace is where most affairs begin.
Previous litera- ture has identified characteristics of the partner involved in infidelity; this study investigates the Big Five personal- ity traits (openness, conscientiousness, extraversion, agreeableness, and neuroticism) of uninvolved partners.
Lack of commitment is the most common reason given by divorcing couples according to a recent national survey. Here are the reasons given and their percentages: Lack of commitment 73% Argue too much 56%
survived the dreaded two-year mark (i.e. the most common time period when couples break up), then you're destined to be together forever… right? Unfortunately, the two-year mark isn't the only relationship test to pass, nor do you get to relax before the seven-year itch.
While love is a source of immense joy, it also tests our patience and emotional resilience in ways we don't always anticipate. This is where the “24-hour rule” proves invaluable. It's the deliberate practice of giving yourself a full day to process your emotions before responding to a triggering event or conversation.
In a relationship, pocketing means one partner keeps the other hidden from their friends, family, and social life, treating them like a secret or something kept "in their pocket" rather than integrating them into their world, often signaling a lack of commitment or shame. This involves avoiding introductions, keeping the relationship off social media, and making excuses for why the partner can't meet important people, making the hidden partner feel isolated and questioning their worth.
Soft cheating (or micro-cheating) involves subtle, often digital, behaviors that cross relationship boundaries and breach trust without being full-blown infidelity, like excessive social media interaction with others, hiding messages, or maintaining secretive contact with an ex, often stemming from a need for validation but eroding intimacy and causing insecurity.
Affairs often start subtly, beginning with emotional disconnection, unmet needs (like feeling unseen or unappreciated), and blurred boundaries, frequently blossoming from friendships, especially at work, through shared frustrations, lunches, or social media, evolving from mental/emotional intimacy to secrecy and physical betrayal as individuals seek validation, novelty, or a lost sense of self, rather than a happy person usually seeking an affair.
But it does provide some rough guidelines as to how soon may be too soon to make long-term commitments and how long may be too long to stick with a relationship. Each of the three numbers—three, six, and nine—stands for the month that a different common stage of a relationship tends to end.
There isn't one single "best" predictor of cheating; rather, it's a combination of factors, with relationship dissatisfaction, low sexual satisfaction, mismatched sexual desire, and poor communication being the strongest predictors, often alongside individual traits like insecure attachment styles, impulsivity, and a history of infidelity. Ultimately, a lack of emotional connection and unresolved relationship issues significantly increase the risk, according to this Psychology Today article, this National Institutes of Health article, and this Medium article.
Most Start in the Workplace. Here is the unfortunate part: 90% of affairs start in the workplace. So, if a spouse is to have an affair, there's a 90% chance they will meet their affair partner at work. Sometimes it generally starts as casual conversation.
