Does infidelity mean it’s over?

Will infidelity and a cheating partner really kill your marriage? Does cheating meant it's over?

Infidelity. Cheating. Adultery. An affair. Whatever term you use, it’s a devastating event in a marriage or partnership.

DEFINITION: Infidelity is defined as sex outside a marriage or primary relationship, unless the relationship is expressly open in nature.

Yet emotional infidelity can be just as damaging to a marriage and for many, the emotional aspect of an affair is more devastating than the physical. Most affairs incorporate both emotional and physical aspects.

How common is infidelity?


  • According to Sexual Health Australia, up to 70 per cent of all marriages will experience an affair.
  • 60 per cent of men polled admit to having an affair at some point in their marriage – yet most claim to be happy within their marriages.
  • 45 per cent of women polled admit to having an affair at some point in their marriage, with fewer happy in their marriage than men who cheat.
  • Internet affairs are becoming more prevalent.
  • People are more likely to be unfaithful during a challenging period in their relationship.
  • A staggering 2-3 per cent of children are the product of infidelity (Anderson, KG: Current Anthropology48)
  • Infidelity is becoming more common in people under the age of 30.
  • The biggest deterrent for many people against having an affair is the possibility of being caught.
  • In many cases, infidelity goes undiscovered.


Why do people cheat?

The decision initially to be unfaithful is rarely rational, and most people who are unfaithful are initially driven my momentary emotions and circumstances – and are surprised by their behaviour at the time.

Men and women tend to be unfaithful for different reasons.

Men are often seeking out physical satisfaction outside the marriage (even when they are satisfied sexually in the marriage), whereas women tend to be looking for emotional benefits. (Men don’t seek emotional intimacy in an affair as a general rule).

Men who cheat tend to do so more and with more people, yet a woman is more likely to end a marriage as a result of her affair. Put simply, men see affairs as being simply sex-based, while women seek a significant emotional involvement from having an affair.

The main justifications for having an affair are:

  • Sexual – excitement, novelty, variety.
  • Emotional – enhancement to self-esteem as well as companionship.
  • Extrinsic – for career advancement or revenge on a partner.
  • Love – affection and falling in love. Many people find a more suitable partner after they are already married.


Whatever the reason for an affair, the effect on a marriage can be devastating.

The partner of the cheater can experience hurt, pain, anger, betrayal, depression, and shame.

The unfaithful partner may feel invigorated, but will also feel guilt for hurting their spouse. The couple will often then experience erosion of trust, mood swings, intense arguments, sleep and eating disturbances, and anger and depression.


Does cheating mean divorce?

Interestingly, though the overall rate for divorce in Australia is close to 50 per cent, fewer than 20 per cent of divorces are due to infidelity. In fact, according to research, more than 30per cent of marriages survive the discovery of an affair.

There is much that holds a successful marriage together, and other connections can be enough to save the relationship if both parties are willing and able to work through the betrayal.

Factors including shared experiences, strong emotional bonds, children, belief in the future of the relationship, and commitment to each other can save the marriage.

To survive:

  • The unfaithful party needs to be actively willing to change.
  • The betrayed party needs to be willing to forgive.
  • Both partners need to be patient.
  • Both partners need to be willing to acknowledge and confront any issues that precipitated the affair.


With hard work, counselling and commitment, couples who are willing to can find a new basis on which to rebuild their damaged relationship and avoid a divorce. If not, divorce is the likely outcome – and for many this is the only way forward.
