Psychology provides valuable insights into human behavior and relationships, especially when it comes to pair bonding. 

If you’re wondering whether a man will stay by your side, this article has the answers. 

Something to keep in mind: 

Frequently, love can obscure a person’s vision, causing them to overlook warning signs of potential infidelity.

At other times, you may feel doubt about somebody that’s actually unwarranted suspicion and fear from the past. 

This assessment breaks through emotional or temporary judgments and looks at the psychological truth behind a man who’s likely to cheat and one who won’t. 

Here are the signs he’s a keeper who won’t stray: 

1) He’s honest (even about the small things)

How honest is he about the small things? 

This is a crucial indicator of loyalty.

Observing how someone values truthfulness reveals much about their character and integrity.

When he’s honest about all areas of his life and the friends and acquaintances he has, it means he’s much less likely to sweep something under the rug.

If you have to pry things out of him, by contrast, or get him to open up, he’s more likely to end up cheating.

“Being honest and open refers to what you agree to tell each other about your relationships with other people,” notes former clinical psychologist and professor Dr. Catherine Aponte Psy.D.

“This can include mentioning that you are attracted to and may have fantasies about another person.”

2) He has fairly good self-control (even under pressure) 

The ability to restrain impulsive behavior tells you a lot about a man’s character. 

Can he hold himself back from something he wants like eating more snacks or buying things in a cool shop?

Or does he just go for it?

What about if he’s under pressure or there was a really good sale on in that shop or nobody was watching how much snacks he ate: would he just go for it? This tells you a lot… 

As psychological researcher Emily Britton of the University of Waterloo discovered in this 2023 study on self-control: 

“Successful resolution is more likely when people feel less pulled towards temptation and use any type of self-regulatory strategy. 

“Furthermore, successfully exercising self-control is strongly linked to how people view their ability to self-regulate more generally.”

In other words, self-control tends to become a self-fulfilling prophecy. 

3) He’s loyal in many areas of his life (not just romantically)

Partners who exhibit steadfast loyalty in familial, social, and professional contexts are much more likely to be loyal in the long-term. 

When he’s loyal to his friends and work colleagues, he’s also likely to be loyal to you. 

This shows his deeper commitment to relational integrity: he doesn’t stay faithful to those in his life out of obligation or a social custom, he does so out of his own decision and choice. 

“A faithful person is faithful because he chooses to be faithful. 

It is an irrefutable lifelong principle, an internal decision he makes, and it doesn’t depend on you,” notes Anita Krysko.

4) He’s highly self-aware (even about his shortcomings) 

Men with a lot of self-awareness acknowledge their strengths, weaknesses, and vulnerabilities without putting on a brave face or trying to look more stable than they are. 

They also recognize personal triggers and vulnerabilities when it comes to their love life, sexuality and emotions. 

When those triggers occur they know how to resist giving in or engaging in escapism or cheating in an impulsive way: 

As psychologist Dr. Tequila Hales points out

“The scorching repercussions that often come with the aftermath of cheating in a relationship are not considered until after the fact. 

“Cheating men have a visible proclivity to be reckless.”

5) He respects other people’s boundaries (even when he doesn’t get it)

Men who honor other people’s independence and differences are likely to stay loyal in the long term. 

For men who do whatever they want or give in to their own darker impulses, boundaries are negotiable:

But for men who truly respect the boundaries of others (even if they aren’t sure why those boundaries exist or are confused) are loyal partners.

“One of the most common reasons men cheat on their partners centers on darkness in their heart or mind, where factors including lust, pride, the enticements of an affair, and personal frustrations with their partner or life, in general, make them susceptible to being unfaithful,” explains counselor Eric Gomez.

They have faced the darkness inside rather than just doing whatever they decide in any given moment. 

Which brings me to the next point: 

6) He’s faced his personal shadow (and knows it’s no joke)

The “shadow” as psychologist Carl Jung described it, is a place of repressed fears, desires, and traumas.

A man who will always be faithful to you has cultivated self-awareness and confronted his shadow. 

He knows the darker side of his nature and doesn’t let it take him over because he understands its motivations and fears. If there’s a fight between you, for example, he will resist the urge to lash out and “get you back.”

He won’t take revenge by cheating, unlike some men who may “cheat to get revenge, as sexologist and psychotherapist Dr. Robert Weiss, Ph.D., LCSW explains.

7) He opens up about how he’s doing (even when he’s bored or down)

Men who communicate openly and honestly demonstrate a stronger likelihood of remaining faithful. 

He’s voluntarily willing to engage in transparent dialogue and doesn’t keep his emotions or desires locked inside. 

Some men do, which ends up causing a lot of cheating because they’re not being honest about feeling bored or in need of a thrill. 

Psychologist Dr. Carolina Estevez explains it well

“Some men just cheat in order to have novel and thrilling experiences. 

“They’ve become tired of their existing relationship and crave the excitement of something fresh and novel.”

8) He admits to sexual temptation and fantasies (even when he knows it could annoy you)

Denial or dismissal of the possibility of cheating is ironically a sign of a guy who’s likely to cheat. 

Mature men admit temptation and acknowledge their own sexual desires and fantasies. 

They also are willing to be open and frank about what being sexually loyal means to them, which isn’t always clear between couples (a lack of clarity that can lead to heartbreak). 

As Dr. Aponte notes:

“What does sexual fidelity mean to the two of you? What about “lusting” after someone, pornography use, emotional and/or sexual relationships that happen on the Internet?”

This ties directly into the next sign of a loyal guy:

9) He’s in touch with his sexuality (and not playing a socially conditioned role)

Men who openly communicate their sexual desires and boundaries are less likely to seek fulfillment outside the relationship. 

By contrast, men who have an ashamed or secretive attitude around sex are more likely to hide when they’re unsatisfied or have unusual desires and then to seek pleasure outside the relationship. 

As psychotherapist Mark O’Connell explains

“Rather than risk the shame of exposing their desires and getting rejected, many men decide to have it both ways: 

“A safe, secure, and loving relationship at home; and an exciting, liberating sexual relationship elsewhere.”

10) He’s aware of how family and childhood trauma affected him (even if it’s unpleasant)

This guy knows how his early childhood trauma and experiences shaped him and he’s honest about it. 

This is especially the case when it comes to low self-esteem or self-doubt.

He doesn’t try to hide that or seek out validation for it from other women (or friends or habits). 

“Cheating can temporarily increase these men’s self-esteem and make them feel desirable and beautiful, which can be a pleasant diversion from the feelings of inadequacy and insecurity they frequently suffer,” explains Dr. Estevez

11) He doesn’t suffer from a martyr or savior complex (and he knows what they are)

A man who cheats often feels like a victim who’s entitled to get what he wants or a savior who has special perks for his service. 

A loyal guy engages in neither delusion of being extremely “special.”

Dr. Weiss calls this a delusion of “terminal uniqueness,” on the part of some men, explaining that:

“He may feel like he is different and deserves something special that other men might not. 

The usual rules just don’t apply to him, so he is free to reward himself outside his primary relationship whenever he wants.”

Forever is a long time

The likelihood of a partner remaining loyal hinges on their commitment to honesty, communication, self-awareness, and respect. 

It comes down to how honest they are with other people and most of all, with themselves. 

By evaluating these key traits I’ve outlined above, you can gain valuable insights into whether a guy will stay loyal to you

Forever is a long time, but with love, communication and honesty it can be a time of togetherness unbroken by lies or betrayal.
