By TruthScouts Team · Updated July 8, 2026

When we think of infidelity, our minds often jump straight to secret romantic affairs. But infidelity can creep into a relationship in more ways than just the physical. 

There are many types of infidelity and cheating, from emotional cheating to physical cheating. All these types will be a bump in your relationship or marriage if you find out that your partner has involved themself in them. 

While most relationships categorize physical intimacy with lovers as the only form of cheating, research shows that most women will get more upset when they find out about their partner’s emotional cheating. Research shows that 57% of marriages that end in divorce are due to infidelity.

 In this blog, we'll break down the different types of cheating & infidelity so that you can know if your relationship is in jeopardy.  

types of cheating

1. Opportunistic Infidelity:

You may be wondering why people in happy marriages or relationships cheat. Opportunistic infidelity is the reason. It occurs when your partner is still attached to you and still loves you, but the temptations and opportunities make them cheat on you.

Opportunistic infidelity is driven by circumstances that make cheating easy for them. Opportunistic infidelity is common in workplaces, with colleagues who spend more time together and away from their partners.

Cheating does not always occur due to issues or dissatisfaction in a current relationship. It may happen even when your partner gets intoxicated and succumbs to temptation when an opportunity presents itself. 

According to the LA Intelligence Detective Agency, between 30 and 60 percent of married individuals will engage in infidelity at least once during their marriage.

Consider Peter, who offers his female workmate a ride home one evening after a busy workday. They decide to pass by a local restaurant for some coffee but take a few more drinks. Under the temptation, both can easily succumb to them and take advantage of the opportunity.

The effects of opportunistic infidelity are so severe to the cheater that they will feel guilt after the act, especially when they are in love with their partner so much.

2. Financial Infidelity

Financial infidelity refers to secretly engaging in activities that go against agreed-upon financial goals or behaviors within a relationship. 

This can range from small purchases hidden from a partner to large-scale debts or investments made without the other’s knowledge or consent. At its core, financial infidelity breaches the foundational trust that relationships, especially those involving shared financial responsibilities or goals, are built upon.

3. Physical Infidelity:

Physical infidelity, often the first type that comes to mind when we think about cheating, involves engaging in physical or sexual activities with someone outside of one's committed relationship. 

This can range from one-time incidents to ongoing encounters and might occur with or without an emotional connection to the other person.  Recent stats reveal that about 30-40% of unmarried relationships encounter physical infidelity, while around 18-20% of marriages also face physical cheating. 

Often, physical infidelity does not involve emotional attachment. It can be purely physical, driven by physical attraction or desire for novelty, without the deeper emotional connections typically associated with romantic relationships.

4. Emotional Cheating:

Even though emotional cheating does not involve sexual intimacy with the affair partner, it undermines the relationship. 

If your partner is in an emotional affair with someone, they invest a particular closeness to someone else and cultivate a non-sexual intimacy with them. People emotionally cheat on their partners when they are lonely and feel their partner cannot end the loneliness by being close and friendly. 

 A 2023 study involving 90,000 participants found that 91.6% of women and 78.6% of men confessed to engaging in emotional infidelity. 

Emotional cheating can quickly turn into a sexual affair. This makes emotional cheating just as threatening as any form of cheating. Even if it does not reach the sexual phase, the effects of emotional cheating are so severe to a relationship when discovered. Most people claim the impacts of emotional cheating are so intense than physical cheating.

5. Cyber  Infidelity:

An online affair that occurs on dating sites, texts, emails, and chats. Even when the parties involved are anonymous or communicate to the point of meeting up, it is still one common type of infidelity. It is estimated that between 20 and 33 percent of internet users engage online for sexual purposes. Most users are males, approximately 35 years old, married with children, and well-educated.

Sometimes, it also occurs between individuals who know each other, friends, and your partner. Even if the affair partners do not meet in person, the emotional affair is often enough to cause issues in their committed relationships. For this type of infidelity, it's best to try out a reverse phone lookup and reverse email lookup services.

6. Conflicted Romantic Infidelity

Yes. It is possible to love more than one person at a time. When this happens, your partner may cheat on you with the other person and still love you. 

Despite our beliefs that there is only one true love, many have claimed that there are different types of love. Your partner may love you for your personality and character, which you blend so well with each other, but they still connect their sexual desires and emotions with another person. 

They love their affair partner for the sexual experiences. Most people in this situation are deemed selfish since they fear ending one relationship for another because both partners fulfill their desires differently.

Conflicted romantic infidelity is so complicated that cheating partners do not know how to end an affair.

7. Object Infidelity:

Object infidelity occurs when one partner becomes overly engrossed in activities or interests outside the relationship to the extent that it becomes a primary focus, neglecting the emotional and physical connection with their partner.

8. Romantic Infidelity:

Affairs may also be romantic and turn out to be “matters of the heart.” Romantic affairs occur when your partner has little emotional attachment towards you. 

They may blame love for fading. The connection and the intimacy you used to share are no longer there. Although they may be committed to marriage and make it work out, they may find romance elsewhere. This is due to the urge to connect with someone of the opposite sex, something missing in their relationship.

Most romantic relationships, however, are just short-term and do not lead to breakups due to commitments.  Most of the other types of infidelity, including physical, emotional, micro-cheating, and conflicted romantic infidelity, eventually lead to romantic infidelity.
