In almost every survey about what singles look for in a partner, faithfulness, loyalty, and trustworthiness are at the top of the list. In other words, people in committed relationships want a partner who won’t cheat on them. Unfortunately, many relationships end painfully because this desire isn’t always met.
While it’s difficult to obtain accurate statistics on cheating, researchers generally agree that 30 to 50 percent of men and 20 to 40 percent of women are unfaithful. It’s impossible to guarantee that your partner won’t cheat, as people and circumstances change over time. However, you can look for specific personal qualities that indicate a strong predisposition for faithfulness rather than unfaithfulness.
12 signs a man will always be faithful, according to psychology:
- He keeps his word in other areas
Reliability and trustworthiness in various aspects of life are good signs of faithfulness in a relationship. According to major psychological theories, trust is a crucial quality for building and sustaining long-term romantic relationships. Research from the National Library of Medicine has confirmed the importance of trust in romantic relationships. It shows that high levels of self-reported trust in the romantic partner are linked to love and happiness, a positive perception of relationship quality and daily interactions, pro-relationship acts, and a feeling of commitment to the relationship.
- He likes your friends but keeps a respectful distance
Researchers from The University of Victoria in Canada found that nearly half (45 percent) of men and more than one-fourth (26 percent) of women are attracted to friends of their partners and are tempted to act on it.
- He does not keep secrets
Small secrets can blossom into big ones down the line. Research indicates that preoccupation with secrets takes a toll on mental health. Evidence suggests that keeping secrets from one’s romantic partner may harm the relationship as it implies a lack of trust that one’s partner will be supportive.
- He is aware of the danger zones
For instance, business trips are particularly troublesome: In a survey from The Institute for Family Studies, thirty-six percent of men and 13 percent of women said they gave into temptation on a business trip.
- He has extinguished old flames
Many people fondly remember past relationships and some even stay friends with an ex. However, it’s wise to be cautious about too much interaction with an ex. According to The Normal Bar, a survey of over 100,000 people, 32 percent of women and 21 percent of men who gave in to temptation did so with a former boyfriend or girlfriend.
- He is invested in maintaining a friendship, as well as a romance, with you
Many individuals who get involved in affairs have been unable to deepen their love relationship beyond the early phase of infatuation and adrenaline rush. According to research from the American Psychological Association (APA), romantic relationships may be more fulfilling if they look more like friendships. An analysis of nearly 8,000 respondents to the British Household Panel Survey showed that life satisfaction was about twice as high among people who said their spouse was also their best friend.
- He maintains proper boundaries with co-workers
That’s because research says 60 percent of affairs start at work. And keeping a strictly professional relationship with co-workers is how to know if a guy won’t cheat on you.
- He feels appreciated
And this is where you can make a huge difference: More than 90 percent of men, and a similar number of women, said that feeling unappreciated and unwanted contributed strongly to their affairs. Research has shown that feeling appreciated by one’s partner is essential to maintaining reciprocal prosocial relationships. Feeling appreciated by one’s romantic partner indicates that the partner cares about and is willing to meet one’s needs, instilling further prosocial motivation.
- He is not a narcissist
People with narcissistic tendencies — self-absorbed, lacking empathy — are especially prone to straying. Narcissists’ romantic relationships are reported to be transitory, which means lacking in commitment. According to researchers, the link between narcissism and commitment to the romantic relationship partner indicates a negative correlation. That is, narcissism is associated with a game-playing love style, low commitment, and infidelity. Prior research has also shown that narcissists in long-term romantic relationships demonstrate low levels of commitment, are susceptible to infidelity, and have a more significant number of divorces than non-narcissists.
- He doesn’t have an excessive need to be admired and liked
A need to have one’s ego boosted leads to inappropriate relationships with someone eager to flatter. Research has linked social media use to a reliance on external validation, which could lead to self-doubt and the need to feel liked by others.
- At the appropriate time, he will be completely open about finances
Since money disputes are the number one cause of divorce, psychologists have coined the term “financial infidelity,” in which individuals deceive their partner with hidden debt, secret credit cards, and undisclosed shopping sprees.
- He has a strong emphasis on “we,” not “I”
Faithful partners recognize the value of preserving the relationship’s love and intimacy — and will take measures to protect the special bond they share.
