Do Cheaters Cheat Again? 18 Signs They Can Cheat Again

By TruthScouts Team · Updated July 8, 2026

Is the phrase “once a cheater, always a cheater” true?  According to stats, around 15% of couples break up due to infidelity. 

But do cheaters cheat again after having an affair in the past? For couples trying to rebuild their relationship after infidelity, it can be a difficult path towards healing. 

With the possibility of cheating again still at play, you become vigilant about the signs of a cheating partner.  It also becomes hard to trust a partner who has infidelity in the past.

“Once a cheater, always a cheater” may be false. This phrase underestimates a person’s ability to change after infidelity. Some people have changed to become better partners after committing infidelity, and others have learned the lessons and turned out to be better people in their next relationships.

Unfortunately, some cheaters still find themselves cheating on their partners, even after the previous incident.

Signs That Cheaters Cheat Again

Watch out for signs suggesting your partner may be a serial cheater.

1. The Past Predicts the Future

Any person healing from infidelity always tries to find out the cause in the first place. Even after healing and you find out that your relationship is still going through the same experiences and emotions that led to cheating, you may want to be vigilant.

If your partner loses their focus and does not care about building the relationship, they may find it hard to commit again.

2. Your Partner’s Relationship History

Some people have a history of moving from one relationship to another quickly after their breakup. They do not even mind healing. This could be a red flag if you are in a new relationship with such a person.

Such partners do so for fear of being alone, and when they find someone they think is better and likes them, nothing, even their relationship, will stop them from cheating. 

This pattern can repeat itself if they keep moving from one partner to another. 

Daily Life Examples:

3. Unwillingness to Heal

If your partner is willing to work and rebuild your relationship, take responsibility, change, and manage the after work, they may not cheat again. But if they do not show any sign of concern, their lies continue, and they do not invest much into healing, they may cheat again for having little remorse about their actions.

4. Blames You for Cheating

An unfaithful partner who blames you for cheating in the past will not likely change and may cheat again in the future. Such partners may also blame outside temptations for their straying behavior. 

If your partner cannot take full ownership without blaming you or any other external force, they may still be vulnerable to cheating in the future.

Daily Life Examples:

5. They Do Not Feel Guilty

If your partner is not remorseful about the pain they caused you for cheating, they may not likely change. Feelings of guilt always motivate change. 

Even by the thought of cheating again, a guilty partner who cheated knows how it may hurt you. They recognize the consequences of cheating from their past actions and try to improve.

6. They Cannot Reassure You of Their Behavior

After your partner cheats, they must create a healing space for the relationship. Their actions should assure you that they have changed and are willing to make things work again in the relationship. But if this is not the case, they may stray again in the future.

A partner who may not cheat again will always verbally reassure you of their willingness to change and will still work to earn your trust again. It may be a red flag if they cannot give you this verbal reassurance.

Daily Life Examples:

7. They Are Not Patient With Your Healing Process

Healing after infidelity takes time. A partner who cheated on you must always understand what you went through because of their cheating behavior and give you time and space to heal.

A changed partner will acknowledge and be kind of the process and try to save your relationship.

If you notice that your partner does not show compassion for your healing process and blames you for playing the victim, they may be trying to divert their responsibility and the needed change.

8. Gaslighting

A serial cheater will most probably have a gaslighting behavior. When you try to question them about anything, they turn their rage and anger back to you and dismiss your concerns right away.

This is a strategy to divert their responsibilities and avoid the blame and feelings of guilt. Gaslighting could also be a sign that they are already having another affair; this is why they do not want to face and answer your questions.

Daily Life Examples:

9. If They Disrespect the Resolutions

It is only natural to make resolutions and set boundaries after your partner has cheated. Resolutions help in the healing process of a relationship as they tend to help you avoid previous acts that led to infidelity.

If your partner does not seem to respect the resolutions, they may have issues committing themselves back to the relationship.

If your partner breaks the set boundaries and repeats the exact mistakes that led to their straying behavior in the past, it may be the beginning of another cheating incident.

10. They Keep on Flirting

Regardless of what qualifies as cheating in your relationship, flirting always leads to sexual encounters. 

Although your relationship can term flirting as not an act of cheating, it can eventually lead to it. If your partner still flirts with other people after infidelity, there may be a reason behind it. It is the foundation of many infidelity cases that have been reported. 

Daily Life Examples:

11. Blaming Others: 

When someone points fingers at everyone but themselves, it's like dodging a bullet instead of facing the music. If your partner's always playing the blame game, saying it's because of stress, or because you weren't giving them enough attention, well, that's a red flag waving in your relationship wind.

If they consistently blame external factors for their past infidelity instead of taking responsibility, it suggests they haven't fully addressed the underlying issues.

Daily Life Example:

12. Disrespectful Behavior: 

When someone consistently disrespects you or the idea of loyalty in a relationship, it's like waving a red flag. It hints at something deeper brewing beneath the surface. 

Maybe they're not fully invested in the relationship or struggling with their own issues. Whatever the case, it's crucial to address this behavior head-on and figure out what's going on before things escalate. After all, every relationship deserves mutual respect and trust to thrive.

Daily Life Example:

13. Justifying Infidelity: 

It may be a red flag when someone in a relationship uses justifications or blame-shifting to avoid taking responsibility for their actions. It suggests a lack of awareness of the harm their actions have caused to their partner and the relationship. 

This conduct may indicate a resistance to change and a greater chance of cheating in the future. If individuals want to prevent further infidelity and strengthen their relationships, they must take responsibility for their actions and work towards rebuilding trust.

14. Fantasizing About Others: 

Although you are in a relationship, it feels like your partner thinks about someone else more often than you would like. These indications may point to a wandering eye, such as fantasizing about a coworker or subtly expressing dissatisfaction. 

Indeed, harboring fantasies of being with someone else or quietly criticizing your partner might be telltale signs of trouble. They appear only partially committed to their current journey, as if they are already eyeing the next one.  

Daily Life Examples:

15. Impulsive Behavior:

Someone who frequently follows their feelings without thinking through consequences may find themselves going down the same tempting paths that previously resulted in adultery. Similar to driving without brakes, things may swiftly get out of control and leave a path of hurt and betrayed trust. 

Daily Life Examples:

16. Emotional Distance: 

When your partner begins to emotionally distance themselves, it's one of the telltale symptoms that they might cheat again. This implies that they may come out as cold or uninterested in the relationship, with little regard or consideration for your emotions. According to The Knot, 6% of American couples report being "desperately unhappy" in their relationships.

This behavior can be a sign that they're looking for emotional fulfilment somewhere else. It's critical to talk honestly and confront your partner if you observe them becoming emotionally aloof in order to determine what could be causing this behaviour shift.

Daily Life Examples:

17. Secretive Behavior: 

Behaving secretively can be a warning sign in a relationship. Your companion may be hiding anything if they are constantly watching over their computer or phone. 

A recent report reveals that 1 in 7 married individuals have considered divorce because of their spouse's postings on Facebook or other social media sites.The distance and trust that this secrecy might cause can hinder the building of a strong, honest relationship. To make sure that both partners feel respected and appreciated, it's critical to have open communication about expectations and boundaries.  

Daily Life Examples:


18. Emotional Instability: 

It like riding an intense emotional rollercoaster with extreme ups and downs. Someone who finds it difficult to control their emotions may turn to other people for solace and approval. 

Recent statistics show that poor communication is the reason 25% of partnerships end in divorce. Think of yourself as being on a never-ending emotional seesaw where anything can throw you off balance. Because of this volatility, individuals may find comfort in the attention of others, which can make it difficult to remain faithful and devoted in a relationship.

Daily Life Example:

Wrap Up:

According to a report, 70% of all Americans engage in some form of infidelity at some point in their lives.  However, if they are giving much effort and are working to rebuild their relationship and earn back their trust, they may have changed and most likely will not cheat again. Cheaters cheat again if they show these 18 signs in their relationship.

Always be on the lookout for these signs if you want to know whether your partner is vulnerable to cheating. Infidelity not only ruins your relationship but also disrupts your peace of mind, which can take years to recover from. So, rather than enduring that pain again, it's better to step back before things spiral out of control.
