Suspicions of your husband or boyfriend cheating can be very distressing and cause a whirlwind of emotions.
Whether it’s a gut feeling, changes in behaviour, or unsettling discoveries, knowing how to tell if your man is cheating sexually or engaging in actions that breach the boundaries of your relationship is essential for your peace of mind and well-being.
It empowers you to make informed decisions and guides you toward seeking the support you need during this challenging time.
13 Signs Of Possible Sexual Cheating

Cheating can manifest in various forms and is not always obvious. Here are 13 signs that may indicate possible sexual cheating, each explained in more detail with examples to provide a clearer picture.
1. Sudden Changes In Sexual Behavior
Sudden changes in sexual behaviour can be problematic for any couple. These changes can take many forms, such as a sudden increase or decrease in sexual interest.
Your partner might introduce new techniques or preferences that you have never experienced before, which could suggest that external experiences have influenced their desires.
Changes in sexual behaviour can create a noticeable emotional and physical distance between couples. It can also alter who initiates sexual activity and how it’s communicated, which can be indicative of a changing emotional and physical connection.
Mismatched sexual preferences can lead to tension and frustration in the bedroom. It’s essential to approach this situation with empathy and open communication rather than immediately assuming infidelity. There could be underlying causes, such as stress, emotional issues, or shifts in personal preferences, which can be addressed together in the relationship.
2. Change In Affection Patterns
A noticeable decrease in the frequency of affectionate gestures like kissing, hugging, or cuddling could suggest a shift in your partner’s emotional connection. When these acts of affection begin to feel routine or forced, it’s a sign that they may no longer be genuine expressions of love.
The lack of spontaneity and emotional warmth in these gestures can further indicate a weakening of emotional intimacy. Changes in public displays of affection, such as a newfound reluctance, can reflect changing feelings toward the relationship.
If you consistently initiate affection without reciprocal warmth from your partner, it could signify their emotional withdrawal from the relationship.
3. Mood Swings And Emotional Distance

Frequent and intense mood swings can also be a sign of internal conflict, possibly due to infidelity. Your partner might be unusually sad or even overly happy. The stress of maintaining secrecy around their affair can also lead to increased irritability, causing them to lash out over minor issues.
You might feel a general sense of distance between you and your partner. This isn’t just about physical space but a feeling that the emotional bond you once shared is weakening. It’s like living with someone physically present but emotionally distant.
4. Constant Arguments Over Little Things
When a partner engages in an affair, they may often start unnecessary arguments over trivial matters, a behaviour that can be attributed to various underlying factors linked to their infidelity.
Firstly, a guilty conscience might drive them to provoke these disputes to shift some of the blame onto their partner and alleviate their guilt.
Additionally, they might use such arguments as a deflection tactic to draw attention away from their cheating behaviour. Furthermore, constant arguing might attempt to create a narrative of a troubled relationship, thus justifying their actions.
5. Secrecy With Technology (Phone Habits)
If your partner begins taking phone calls privately, whispering, or moving to another room—behaviours that differ from their usual open phone conversations—it can signal they have something to hide.
Additionally, a sudden increase in phone security, like changing passwords or adding new features without an apparent reason, may indicate they’re trying to keep certain texts, emails, or call logs concealed.
Regular deletion of messages or call logs and secretive behaviour while using their phone, like turning the screen away or quickly closing apps as they approach, could indicate an attempt to conceal their activities.
6. Altered Schedule And Spending Money

An unexplained change in your partner’s schedule can cause concern. For example, they might start working late frequently, have sudden business trips, or take up new hobbies without involving you.
Additionally, unaccounted-for spending or secretive financial transactions can indicate they are spending money on someone else.
7. Physical Appearance And Grooming Habits
Pay close attention to sudden changes in your partner’s appearance and grooming habits. These changes can be noteworthy if they begin dressing more stylishly, using new fragrances, or unexpectedly joining a gym.
These changes, especially when they deviate from their habits, may suggest that they are trying to impress someone new in their life.
While it’s important not to jump to conclusions based solely on appearances, these changes can indicate that they are investing time and effort into their image for reasons beyond your knowledge.
8. Overly Defensive Behaviour And Feeling Guilty
Guilt can serve as a significant indicator of potential infidelity. Your partner may exhibit excessive defensiveness, be easily startled, or display signs of nervousness, such as fidgeting or avoiding eye contact, particularly when the subject of fidelity is broached.
These defensive reactions can be a way to deflect suspicion or hide their feelings of guilt regarding their actions. Hence, approaching these conversations with sensitivity and empathy is necessary, as there could be underlying reasons for their guilt that require open communication.
9. Change In Social Media Accounts

Increased activity on social media platforms, including the addition of new friends or followers, secretive messaging, or changes in their online behaviour, should not go unnoticed. These changes may signify that they are hiding a relationship from you.
While privacy is important, sudden and significant shifts in their online presence may warrant a discussion about trust and transparency within your relationship.
10. Work Colleagues Interaction
If your partner begins mentioning new work colleagues but provides little information about them or spends an unusual amount of time with these colleagues outside of work hours, it could raise a red flag.
These interactions may be more than just professional, and their vagueness may suggest secrecy.
11. Avoiding Family Members Or Friends
A sudden and unexplained avoidance of social gatherings involving family members or mutual friends can indicate feelings of guilt. Your partner might be apprehensive about being discovered or could be finding it challenging to face these individuals while concealing their infidelity.
This behaviour can strain your relationship with these important people in your life, adding another layer of complexity to the situation.
12. Lack Of Interest In Your Life
A cheating partner may lose interest in your life, including aspects such as your work, friends, or hobbies. This lack of interest can cause them to forget important dates like anniversaries or birthdays as they become more preoccupied with their secrets.
It’s crucial to address this change in behaviour and its impact on your relationship, as it can lead to feelings of neglect and detachment.
13. Change In Attitude Towards The Future
If your partner seems less interested in future plans, like vacations, buying a house, or even simple weekend plans, it could indicate they are reevaluating the relationship. This might be because they are considering a life with someone else or are unsure about remaining in the current relationship.
These signs, while potentially indicative of cheating, are not conclusive proof. It’s important to approach the situation with sensitivity and open communication and seek professional guidance.
What To Do And Not To Do If You Suspect Your Man Is Cheating?

Suspecting infidelity in a relationship can be an emotionally challenging experience. It can evoke various emotions, including anger, sadness, and confusion. However, how you handle your suspicions is crucial for the health of your relationship and your well-being.
What To Do
While it’s natural to feel hurt and betrayed in such a situation, it’s important to approach it with maturity, empathy, and a desire to understand the truth.
- Communicate Openly: Initiate an honest and non-confrontational conversation with your partner. Express your concerns and feelings, allowing them to respond without judgement. Effective communication is key to understanding the situation.
- Gather Evidence: If your suspicions persist, consider collecting evidence discreetly. This may involve documenting suspicious behaviours, messages, or activities. Keep this information confidential until you have a clearer picture.
- Seek Emotional Support: Reach out to friends, family, or a therapist to discuss your feelings and gain emotional support. Dealing with suspicions of infidelity can be emotionally challenging, and having a support system can be invaluable.
- Self-Care: Focus on self-care to manage stress and anxiety. Engage in activities that promote your mental health and emotional well-being, such as exercise, meditation, or hobbies.
- Consider Professional Help: If you believe your relationship is breaking down, consider seeking couples therapy or counselling. A licensed therapist can help facilitate communication and provide guidance.
What Not To Do
By steering clear of these pitfalls, you can maintain a level-headed approach and work towards a more constructive resolution of the issue, whether it confirms your suspicions or reveals a different truth altogether.
- Jump to Conclusions: Avoid making hasty judgments or accusations without concrete evidence. Base your actions on facts rather than assumptions.
- Invade Privacy: While gathering information discreetly is important, invading your partner’s privacy by hacking their devices or accounts is not advisable and may have legal implications.
- Confront Publicly: Avoid confronting your partner in a public or aggressive manner. This can lead to unnecessary embarrassment and damage the relationship further.
- Seek Revenge: Retaliating by cheating or seeking revenge is counterproductive and can escalate the situation. It’s essential to address the issue with maturity and integrity.
- Neglect Self-Care: Don’t neglect your own well-being while dealing with suspicions of infidelity. Remember, it’s not selfish to prioritise your mental and emotional health.
- Make Ultimatums: Making ultimatums or threats can lead to a breakdown in communication. Instead of ultimatums, focus on understanding the root causes of the issue.
- Blame Yourself: Avoid blaming yourself for your partner’s actions. Infidelity is a complex issue, and it’s not your fault if your partner chooses to cheat.
Strategies For Proving Suspected Infidelity
When facing suspicions of infidelity, gathering evidence is a critical step, particularly if you are contemplating divorce. In Singapore, divorce is governed by the Women’s Charter, and one of the grounds for divorce is adultery.
However, simply having suspicions or making accusations is generally insufficient to prove adultery in court. The legal system in Singapore requires evidence that is clear and convincing. Without concrete proof, it can be challenging to establish a divorce case or pursue any legal action.
Therefore, evidence plays a crucial role in supporting your claims and achieving a favourable outcome in divorce proceedings.
- Hire a Private Investigator: One of the most effective strategies is to hire a licensed and experienced private investigator. Private investigators have the expertise and resources to gather evidence discreetly and professionally. They can conduct surveillance, collect photographic or video evidence, and provide credible witness statements if necessary. Their unbiased findings can carry significant weight in divorce proceedings.
- Gather Digital Evidence: Much of our lives, including potential infidelity, can leave a digital trail in today’s digital age. Checking your partner’s communication devices, such as phones and computers, for messages, emails, or photos can yield valuable evidence. However, it’s essential to respect privacy laws while doing so.
- Look For Witnesses: If you are aware of individuals who may have information about the infidelity, consider speaking to them discreetly. Friends, family members, or colleagues who have witnessed or have knowledge of the affair can provide witness statements or testify in court if necessary.
