There's no single "average" for cheaters, but statistics show infidelity is common, with rates varying by gender, age, and culture; studies suggest around 20% of men and 13-20% of women might cheat in a marriage, with higher rates in middle age and significant differences in perceived wrongness of cheating between genders, notes Brides.com and ifstudies.org.

The workplace is where most affairs begin. It doesn't hurt that we usually dress nicely and are on “good behavior” at work. Plus, having shared passions about projects (or mutual annoyance at a boss or co-worker) provides the perfect breeding ground for an affair.

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.
Lack of sexual chemistry is a huge reason people cheat. Often, the person who cheats will say they felt like a friend, roommate, or business partner rather than a lover in their relationship. They want to feel wanted and desired sexually. They also want to experience variety and novelty in sex.
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.
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.
Is Adultery Illegal in Australia? Let's start with the basics: No, cheating is not illegal in Australia. Australia operates under a no-fault divorce system thanks to the Family Law Act 1975 (Cth). This means the court doesn't care who caused the breakup or why.
After cheating, a guy might act distant and secretive (hiding his phone, staying out late) or overly attentive out of guilt, often becoming defensive, irritable, or starting arguments. He might change his routine, appearance, or habits, developing new interests or sudden hygiene changes, and often shows emotional withdrawal, resentment, or stonewalling when confronted, with signs varying based on his personality and feelings about the affair.
The 7-7-7 rule for couples is a guideline for maintaining strong connection by scheduling dedicated time: a date night every 7 days, a weekend getaway (or night away) every 7 weeks, and a longer, kid-free vacation every 7 months, all designed to fight drift and routine by ensuring consistent, intentional quality time, though flexibility is key.
There's no single way that affairs come to light, but the most common way is through accidental discovery. Maybe a partner stumbles upon suspicious text messages, sees an unexplained charge on a credit card, or notices a sudden behavior change.

Many men who cheat still claim to care deeply for their partners, which can create confusion and emotional pain. New research shows that male infidelity is often not about love or attraction but rather may result from unmet emotional needs, or physical intimacy needs, or self-esteem issues.
Sometimes people cheat because they feel emotionally neglected or unappreciated in their current relationship, seeking validation or connection elsewhere. A lack of communication can also play a big role; if needs or issues aren't being addressed, infidelity can seem like an escape.

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.
