Article: Your partner may develop sudden new interests or friends if he or she is cheating.  He or she may begin working longer hours.  If you ask your partner where he or she is going, your partner may give you a vague answer such as "Out." or "Meeting up with some people."  When you try to contact your partner when he or she is out, your partner may send your call to voicemail or not return your text messages.  Your partner may frequently say, "I didn't hear the phone." or "Sorry, my battery died." Note whether this is a consistent pattern, or whether it lasts only a short time. Your partner may well have a project at work taking up more of his or her time. However, s/he should feel comfortable telling you that this is what's happening. If not, this could be a sign that your partner is cheating. Your partner may begin to leave the room to talk on the phone or never leave the phone behind when he or she leaves the room.  If your partner is on the computer, he or she may shut down the computer when you walk by or enter the room.  Your partner may be becoming secretive because he or she feels the need to hide things from you.  Make sure the secretiveness is something new.  If your partner has always been private, it may be more difficult for you to notice anything. If you ask your partner who was on the phone or what he or she was doing on the computer, your partner may respond by saying, "No one," or "It's work related." or "Wrong number." or "Why are you asking?" A person may feel guilty or more irritable when he or she is having an affair.  Keeping a secret can take a toll on a person. To deal with his or her feelings, a cheating partner may start fights with you, criticize you, or even accuse you of cheating.  A cheating partner will try to make you feel bad about yourself or that you have done something wrong.  During arguments, your partner may try to make it seem like you are the problem in the relationship instead of him or her.  Remember that your partner is acting this way because of the lie that he or she is living. You should not feel guilty about anything. Your partner may become less affectionate when he or she is having an affair and pull away from you if you try to show affection.  Your partner may not initiate sex or feel distant even when you do make love.  Your partner may no longer greet you with a hug or a kiss or may not be interested in holding hands.  An increase in your partner's sex drive or an interest in trying different sexual things may also be a clue. If you tell your partner that you have noticed a difference, he or she will probably deny it or suggest that you are being sensitive or unreasonable. Has your partner started going to the gym more or changing his or her diet?  Has your partner gone shopping for new a wardrobe or began wearing different cologne or perfume? Your partner may also buy new clothes but never wear them around you.  He or she is probably trying to look good for someone else. Notice if your partner smells differently when he or she comes home as well. Check the phone when your partner is sleeping or in the shower. You do not want to get caught snooping. Look through the call log and text messages for names or number that you are not familiar with.  If your partner is smart, he or she may delete text messages and clear his or her call log.  You can also check email, Facebook, or Twitter.  See if there has been any contact with new people. If you have access to his or her computer, check the web browsing history as well. Check his or her phone for dating apps (e.g., Tinder, OkCupid, Plenty of Fish, etc.) as well. These could be used to meet other people. If your partner deletes his or her call log, you can get call records from the phone carrier. Going through your partner's phone is an invasion of privacy.  If your partner is not cheating, he or she may feel betrayed by your lack of trust. A cheating partner often stops putting effort into the relationship.  He or she may no longer take interest in your life or feelings. Your partner stops offering you emotional support. For example, you may tell your partner about an issue that you are having at work or at school, and he or she may tell you it's not a big deal.  Your partner may not be interested in discussing the future of the relationship or making future plans. If your intuition is telling you that something is off in your relationship, listen.  Science has shown that people can tell if their partner is cheating. You should not rely on your gut alone. However, if you have a feeling, begin paying attention to any other signs that your partner may be cheating.
