Innocent people can react to false accusations of cheating can in a variety of ways. Common reactions include surprise and disbelief, denial of the accusation, anger and frustration, a desire to prove their innocence, and a willingness to cooperate with any efforts to investigate the situation.
The physical signs of cheating are the most obvious. This includes spending more time with friends and less with you, avoiding sex, having a random or significantly changed schedule, and changes in their appearance.
The direction of their eyes: A 2012 study published in Plos One debunked the myth people look to the left when lying. A study by the University of Michigan found when participants lied, they maintained eye contact 70% of the time.
Cheaters often react to an accusation of cheating with denial, showing no guilt signs. This can be a simple 'no' or more of a statement of unwillingness to accept the accusation. Whatever the form, denial is likely to be one of the first responses to allegations of cheating.
Cheaters may lie or deny what happened.
They might also say things to make you doubt yourself, like “You're just being paranoid,” or “That's crazy, why would you think that?” This form of deception is called “gaslighting.” Spotting the difference between a lie and an honest denial can be tricky.
If you've been cheated on, it's likely that you also experienced some degree of what psychologists refer to as gaslighting. Gaslighting, in case you're wondering, is a form of psychological abuse that involves the presentation of false information followed by dogged insistence that the information is true.
Cheaters will often use laptops and tablets, and even hidden apps, to communicate with a paramour. A new favorite place for texting is Google Docs. Your partner can claim to be working, rather than sexting with a new lover.
The most important thing to remember is what cheating says about a person. They're insecure, impulsive, selfish, and immature. Sometimes, it's a chronic problem that likely won't ever be fixed, just be sure not to ignore the warning signs.
A cheater might suffer from extremely low self-esteem and a narcissistic view of seeing things. Some people have a tendency for attention-seeking and once they are satisfied with one person they might go on to another to fulfil their needs and validate themselves.
The narcissistic liar
This type of person never admits to making a mistake, even when the mistake could be a growth opportunity for your PR team. He or she is often a "people person" seeking attention when things go right, bragging or exaggerating accomplishments, while being quick to place blame and criticize others.
Sweating or dryness: Autonomic nervous system changes can trigger liars to sweat in the T-area of the face (upper lip, forehead, chin and around the mouth) or have dryness in the mouth and eyes — the person might excessively blink or squint, lick or bite their lips or swallow hard, according to Glass.
They will avoid using pronouns like "I," "mine" and "myself." They may use oddly phrased statements in the third person. For example, they may say, "You don't bill hours that you didn't work," instead of saying, "I don't bill hours I didn't work." Or they'll say, "The vase got broken," instead of "I broke the vase."
Watch facial expressions When people are in the middle of a lie their facial expressions may show you. Look for flared nostrils, lip biting, rapid blinking or sweating. These changes in facial activity signify an increase in brain activity as a lie begins.
Researchers say no. Science shows that liars do not avoid eye contact any more frequently than those telling the truth. The key thing to look for in eye movement is deviation from their baseline.
While the effects of infidelity can manifest in different ways within different relationships, there are some common signs that frequently accompany cheating. Becoming emotionally distant, angry, defensive, or secretive can be hints that they're being unfaithful, as can intense suspicion directed toward you.
In many cases, people think their spouse is cheating on them because either they've cheated on someone in the past or are about to. Psychologists say that projection is a low-level coping skill, where people who cheat or think of cheating are likely to project the same thoughts on their partners.
