A few weeks ago, a friend had a Facebook meltdown. He unfriended his wife, changed his profile photo to black, and announced he was “done.” His wife had gone out with a male friend and didn’t give him the attention he felt he deserved. He was jealous.
Jealousy has caused many problems in relationships throughout history, including murder and other violence. But, more often than not, jealousy simply ruins relationships.
Frustrated friends and coaching clients reach out to me and ask why do guys get jealous? This article will explain his behaviors and provide answers.
Immaturity
When I was in high school, my friend sat next to a girl whose boyfriend went to another school. He and this girl would talk and occasionally flirt, but nothing more happened. A few days later, her boyfriend called him up and wanted to fight him!
Jealousy is more common in adolescents, especially those with lower self-esteem. As guys mature, they usually develop greater confidence and emotional maturity. So, a lot of their teenage habits go by the wayside, including strong feelings of jealousy.
If your boyfriend is younger or generally more emotionally immature, then that could be why he gets jealous. As he matures, you’ll hopefully find that his feelings of jealousy fade. But, sadly, age doesn’t always lead to emotional maturity and people can experience extreme feelings of jealousy at any age.
Insecurity
My friend in the opening story had a history of emotional trauma in relationships. He had an ex-girlfriend who cheated on him when he was younger and he went through a nasty divorce that involved restraining orders and custody battles.
Jealousy not only stems from low self-esteem, but also feelings of insecurity in the relationship. He might feel like you could leave at moment, that you’re better than he is, or that you’re inevitably going to cheat.
Keep in mind, in most cases, insecurity comes from past experience. So, you might have a great bond and an amazing relationship, but his past trauma rears its ugly head in the form of insecurity and he gets jealous.
Let me give you an example. You love your boyfriend and have no desire to cheat. But, his previous girlfriend hooked up with a guy at a bar. So, if you go out to a bar with your girlfriends, he assumes that you are also going to cheat on him. Next thing you know, he gets jealous and ruins your evening with your friends.
Fear
Many people think jealousy is the same as envy, but that isn’t true. Envy is when you want what someone else has. Jealousy is fear that someone else will take what you already have. If you’re asking why do guys get jealous, the answer, at the root is fear, especially fear of being replaced.
He is afraid, for whatever reason, that he is going to lose you to someone else. If you’re talking to a guy at work, he fears that you’ll like that guy better. If you go out without him, he worries that you’ll meet someone new. Ironically, when guys get jealous, they push the woman away and they end up losing her.
The opposite of fear in relationships is trust. If he can fully trust you, then most of the jealousy will fade. He won’t care if you go out with friends or meet a new guy at work because he has total faith that you will still come back to him and be loyal.
Like with insecurity, his trust issues might not have anything to do with you. Most problems with trust go back to the past. So, when he acts jealous, he’s taking all of his past experiences where trust was broken–parents, friends, lovers–and applying them to you and the relationship.
Your Past Behaviors
Jealousy can be very ugly and lead to ugly things. If he gets jealous for no good reason, it can lead to many problems in a relationship. And, no woman has to put up with an insecure, jealous jerk.
But, if you’re wondering why do men get jealous, your behavior might be contributing or have contributed in the past.
If you broke trust by lying to him about exes or even went so far as to cheat on him, that breach of trust won’t easily heal even if he says he’s “over it.” While he might have forgiven you, the worry that you will break trust again leads to jealousy in the present.
He also might feel jealous about aspects of your past behavior. For example, if he knew you cheated on someone else years ago or that you felt a deep love for an ex, those could make him guarded in the present. He fears he will lose you.
Brain Chemistry
Ultimately, jealousy is like anything else related to emotion: a function of brain chemistry. Emotions aren’t logical. When we see something infuriating, we don’t have to talk ourselves into anger. We just feel it. The same is true with love, sadness, and other feelings.
Jealousy appears to come from the brain chemical oxytocin. Oddly enough, this is the “cuddle” chemical that creates loving bonds, like between lovers and even mother and child. However, research has shown that oxytocin can also lead to feelings of aggression and ultimately jealousy.
This research doesn’t surprise me at all. It makes total sense that a chemical that bonds would also make people want to preserve and protect that bond. So, when your bond with a guy is threatened (at least in his head), his brain releases chemicals that make him jealous and aggressive towards potential competition for your love.
In the end, excessive jealousy is toxic and brain chemistry is an explanation, not an excuse. If guys get jealous, they ultimately need to find ways to cope with their feelings, even if it involves getting outside help. Also, you don’t have to put up with toxic jealousy. In the end, it will destroy the relationship and make both partners unhappy.


Whenever friends break up, I always get a call. They are going through a lot of emotions, including love, hate, fear, and sadness. They want to talk to me, not as a dating coach, but as a friend.
Many people, both men and women, prefer a clean break when a relationship ends. So, they might block you or unfriend you on social media and not respond to your texts. This might seem cold or distant, but it’s really just your ex’s effort to move on.
Or, he might feel that you both aren’t good for each other. As much as he feels love, he knows that dating each other is a bad idea. And, if he tries to reconnect with you, it will end in disaster. He stays distant because if he got close, he couldn’t resist and would get into a toxic situation.

But, the truth is that relationships aren’t always that great. Many of them involve abuse, cheating, boredom, and sexual frustration. You don’t see that harsh reality on social media where people hide behind the smiles and positive quotations.
And, guess what that does? It makes you more likely to get into a better and happier relationship by shedding an attitude of neediness and giving you more genuine confidence.
Six months ago, a good friend started dating a guy who seemed incredible. Handsome and charming, he had a good job, a nice car, and made her laugh. She quickly wondered if she had found “the one” and started to fall for him after a few dates.
It isn’t shocking, but being honest
Look carefully at how he spends his time rather than the words he tells you. Is he focused only on himself? Does he spend all of his time playing video games or doing unhealthy or dangerous things? Do others see him as a jerk or loser?
Science has determined a lot about what women want for dating, relationships, and sex. Being “nice” and “following the rules” don’t appear on any lists.
People of both sexes have serious problems and make bad dating choices. Just because a woman comes from a good background or got good grades at once point doesn’t make her a good person or lead to good choices.
A former coaching client of mine was attractive, fun, and flirty. She landed a great job in a large metro area and wanted to meet new people.
It might be shocking to hear, but perhaps the best way to meet men is to not focus on meeting men. Let me explain.
We live in an age of female empowerment. If you think he looks safe and normal, then nothing should stop you from making the first move. At least say “hi” and go from there. If you have a good conversation, then give him your number or ask to add him on social media. Then, see what happens.
You meet a guy you like and text him. Everything is great and you go on a coffee date. You send a text thanking him for a great time. He doesn’t reply.
With online dating, determining attraction is a much longer process. Sure, you see a few photos and a bio, but it takes regular messaging and meeting up to determine if even a small spark exists.
Ghosting sucks, but men do it (women too) primarily because they can. You can speculate on his exact reasons for weeks or months, but, in the end, you might never know.
Online dating gives people a lot of choice. It also creates what is called the “paradox of choice” or “
While these five reasons are good guesses, remember that you might never know exactly why he liked you, but still blocked you. He could’ve blocked you for literally any reason, no matter how ridiculous or awful. You’ll probably never know and must accept that.
We live in an age of instant communication and it’s revolutionized dating. You might have a huge crush on a guy and want to date him, but your anxiety is off the charts because you know that he’s probably texting several other women as you read this article.
Everyone wants to be wanted. If you’re asking how to get a guy’s attention through text, the best answer might be “pay attention to him!”
They’re perfect for flirting. A few of my favorites are the winking emoji if I’m being seductive or the fire emoji if I’m giving a compliment. If I’m suggesting something a little more “adventurous,” I’ll use the angel (or devil) emoji.
For those who are unaware, we are entering that time known as cuffing season. Supposedly, people who normally enjoy the freedom of being single or “dating around” decide to settle into a more traditional relationship during the fall and winter months. They are “cuffed” or tied down to another person.
So, that guy who is content playing video games and hanging out with his friends during the summer will likely see his T levels rise during the fall.
Even if they don’t really want to be tied down, they also might not want to be “that person” who goes stag to holiday parties or appears alone in holiday photos.
