If you're worried that your partner or significant other is being unfaithful, you're not alone. Statistics show that approximately 15% of women and 25% of men have engaged in extramarital affairs. This number rises to 20% when considering emotional or intimate relationships. When you suspect your spouse or partner of cheating, there are numerous signs you can look for to determine if you're a victim of betrayal. Your partner may exhibit unusual or strange behavior, or you might notice changes in their daily routines and spending habits. Detecting infidelity isn't easy, but by observing your partner's actions, you can identify certain signs of cheating and take necessary steps to either repair or end the relationship.
Steps
Evaluate the Relationship

Keep track of relationship details. Reflect on the journey of your relationship to assess whether it still brings satisfaction and happiness to both of you. Often, taking the time to carefully review and think deeply about your relationship can reveal some warning signs that something is amiss.
- The most common warning sign is simply when your spouse tells you that something is wrong, but you dismiss their complaints. Common phrases include, "This marriage isn't what it used to be," "I'm not happy," "I need more."
- More frequent conflicts in your romantic life can indicate trouble in the relationship. Whether this conflict is a result of infidelity or the infidelity is a reaction to an unhappy relationship, frequent arguments with your partner are a sign that your relationship needs improvement.
- Harsh criticism from your partner can be a sign that something is wrong. If your partner often openly criticizes you, such as saying you need to "hit the gym," "lose weight," or "see a doctor," they might be trying to make you feel insecure to justify their cheating.

Observe your partner's behavior. If your spouse is being unfaithful, they might avoid physical closeness or act unusually in intimate situations. They may create distance or appear indifferent toward you.
- Notice if your partner seems disinterested in intimacy. If they are receiving affection elsewhere, they may no longer seek it from you.
- Pay attention to how your partner interacts with you. Do they no longer hold your hand or show spontaneous affection? Physical distance can often signal emotional detachment.
- Be mindful of any unusual changes during intimate moments. Your partner might introduce new techniques they’ve learned or practiced with someone else.

Reflect on your own behavior. Consider whether you’ve been neglectful, indifferent, or rude toward your partner. Be honest in evaluating your actions from their perspective.
- If you’ve been emotionally distant, your partner might seek fulfillment elsewhere. They could be pursuing an affair to regain your attention or prove their desirability.
- If you’ve been preoccupied with work or children, your partner may feel lonely and seek companionship elsewhere.
- If you’ve mistreated your partner, an affair might be their way of retaliating, boosting their confidence, or escaping the relationship.

Trust your intuition. If your gut tells you your partner is being unfaithful, don’t dismiss it. As highlighted in a recent New Scientist article, "our emotions stem from unconscious thoughts," making them more reflective of underlying truths than rational thought. Intuition can often protect us from prolonged suffering. You might be picking up subtle cues from your partner without fully realizing it.

Talk to your partner. If you suspect infidelity, initiate an honest conversation about the state of your relationship. Communication can either confirm your doubts or ease your fears. While you may not get the answers you hope for, open dialogue fosters clarity and understanding.
- Choose a calm and relaxed moment, avoiding times of anger. A negative atmosphere can hinder productive discussion. Frame it as a conversation, not an interrogation.
- Select an appropriate setting. If privacy is key, find a quiet space. If public areas feel safer, suggest a walk or a visit to a nearby park. A neutral location can help ease tension.
- Start the conversation by focusing on your feelings. Use non-judgmental language, such as, "I’ve been feeling uneasy lately," or "I’m concerned about our relationship." Beginning with "I" statements reduces defensiveness.
- Gauge your partner’s willingness to address your concerns. A positive sign is their openness to improving the relationship through dialogue or counseling.

Decide if it’s worth it. If the conversation doesn’t go well or confirms infidelity, take a hard look at your relationship. Ask yourself what you truly need. Is it worth staying with someone you can’t trust? If you doubt your partner’s loyalty or feel they’ve broken your trust, this may not be the healthiest relationship for you.
Pay attention to your partner's external changes

Notice outward changes. Significant alterations in appearance might indicate your partner is trying to impress someone new. These changes could also mean they are actively seeking a new romantic interest.
- Observe if your partner has updated their wardrobe. For instance, if they typically wear casual sportswear but suddenly start dressing in suits or tailored clothing, this could signal infidelity, especially if there’s no major lifestyle change, like a job promotion.
- Your partner might join a gym or increase their exercise routine to improve their physique or lose weight to please a new lover. Their new interest could be someone they’ve met at the gym or a fitness class.
- A sudden focus on appearance and concern about looking attractive may suggest your partner is trying to impress someone else.

Monitor your partner's grooming habits. Your spouse might pay more attention to grooming if they’re trying to attract someone new. While it’s perfectly normal for both men and women to care about their appearance, sudden changes in habits can be a red flag.
- Notice if your partner showers, flosses, shaves, or engages in other grooming activities more frequently.
- Be aware of new makeup, perfumes, or deodorants your partner is using or that linger on them. As the saying goes, lipstick on a collar can expose a cheating man.
- Check if your partner has changed their hairstyle. Have they suddenly altered their look or started dyeing their hair?
Conduct an investigation

Watch for schedule changes. Take note if your partner alters their daily routine. They might adjust their schedule to align with their new lover’s availability or to make time for someone else. These changes could be significant or subtle and sporadic.
- Notice if your partner frequently justifies their plans, such as staying late at work, traffic jams, or other excuses to explain why they’re home less often.
- If your spouse suddenly wants to go out with friends without you, this could be a perfect excuse to leave the house. Pay attention if they no longer invite you to events or company trips.
- Be cautious of sudden business trips or other excuses they create for being away from home for extended periods.
- Additionally, if your sudden absence doesn’t seem to bother them, and they appear indifferent to you working late or traveling, they might be using this time to be with someone else.

Attempt to communicate with your partner. Have you suddenly found it challenging to get in touch with your loved one? If you've tried calling your spouse multiple times without a response, this could indicate a shift in your relationship.
- Your partner might justify not answering the phone. They might claim their phone died, there was a technical issue, or they were in an area with no signal.
- Be cautious if they reassure you they're too busy to answer or suggest you wait for them to call back.
- Has your spouse turned off their phone during times when you could usually reach them? They might have set it to silent to spend uninterrupted time with someone else.

Pay closer attention to unusual or new items left behind by your partner. Sometimes, a spouse might carelessly leave behind evidence of dishonesty, such as a lover's house key.
- Check details on shopping receipts or restaurant bills. Look for contact numbers on receipts. Search for hotel room keys, movie ticket stubs, and similar items.
- Also, inspect your partner's car. Unfaithful partners might hide incriminating items in glove compartments, ashtrays, or under seats.

Monitor your partner's computer activity. Your spouse might be spending more time on the computer, chatting online, or frequently visiting social media sites.
- Examine their social media accounts closely. See if they're regularly communicating with one particular person. Frequent exchanges with an ex could be a red flag.
- Observe if they quickly close windows or apps when you enter the room or if they often clear their browser history.

Review bank or financial institution statements. Your partner might start spending large amounts on activities or gifts for a new lover.
- Look for multiple withdrawal receipts or shopping receipts from stores or places you rarely or never visit.
- Notice credit or debit card transactions from restaurants or bars you've never been to.
Monitor phone usage habits

Observe your partner's attachment to their phone. Mobile phones can make it easier than ever to detect infidelity. If your partner is constantly glued to their phone, they might be using it to communicate with a new lover.

Pay attention to frequent phone usage. Notice if your partner increases their phone activity, such as making more calls or sending more texts. Observe the number of calls and messages received daily. Ask yourself if your spouse used to communicate this frequently during similar times in the past.

Look for a second phone. If your partner is having an affair, owning a secret second phone is a clever move. With a hidden phone, they won't worry about forgetting call logs or messages.
Warning
- Remember that all the above signs could indicate infidelity, but they might also have innocent explanations. Accusing your partner of cheating or being caught investigating them—checking their wallet, phone, or emails—could seriously harm your relationship, even if no issues existed before.
- Both men and women often show similar signs of infidelity. Cheating isn't limited to men, although it's believed that men cheat for sexual satisfaction, while women tend to cheat for emotional fulfillment. Today, with increasing economic and personal opportunities for women, independence among married women is more common, leading to higher rates of infidelity among wives.
