Low self-esteem doesn’t always seem like insecurity on the surface.
Especially in men, it can come out sideways through control, withdrawal, deflection, or trying way too hard to prove something. In relationships, these patterns don’t always scream “I don’t feel good about myself,” but they can have a big impact on how safe, close, or sustainable the connection feels. Here are some of the most common things men might do in relationships when their self-esteem is running low, usually without realising where it’s coming from.
1. They become overly controlling.
When a man doesn’t feel secure in himself, control can feel like a way to protect the relationship, or at least keep something stable. He might start micromanaging your time, getting jealous over little things, or needing constant updates. It’s not always about dominance. Sometimes, it’s fear in disguise, or a way to soothe the voice in his head that says he’s not good enough, and you’ll eventually leave. Unfortunately, it ends up creating the very tension he’s afraid of.
2. They joke about themselves a little too often.
Self-deprecating humour can be charming in small doses, but if it’s constant, it can be a sign that he genuinely doesn’t believe he has value. Jokes like “You could do way better than me” might seem light-hearted, but they often come from a deep place of doubt. Eventually, these comments can wear on a relationship. They don’t invite connection; they push reassurance. When someone keeps making themselves the punchline, it’s usually about more than just humour.
3. They struggle to accept compliments.
Men with low self-esteem often brush off praise. They might laugh it off, change the subject, or downplay what you’re trying to acknowledge. It’s like they can’t quite believe you mean it, or that they deserve it. This might seem like humility, but it can make emotional intimacy harder. When someone can’t receive love without deflecting it, it puts you in the awkward position of constantly having to prove your sincerity.
4. They need constant reassurance.
If he’s frequently asking “Do you still love me?” or “Are you sure you’re happy?” it might be more than just wanting affection. Really, it could be about struggling to believe he’s enough. He might be looking for external confirmation because his internal sense of worth is shaky. Reassurance isn’t bad in itself. However, when it becomes constant, it can start to feel more like emotional labour than closeness. It can leave both people feeling drained and uncertain.
5. They avoid emotional conversations.
Men who don’t feel good about themselves often worry that being vulnerable will expose too much. They might shut down, deflect, or make everything a joke when serious topics come up, not because they don’t care, but because they don’t trust they can handle the emotional weight. This avoidance can leave partners feeling shut out. What looks like apathy is often fear of being seen as weak, of saying the wrong thing, or of not being enough emotionally.
6. They overcompensate by acting “tough.”
Some men mask insecurity with bravado. They might lean heavily into being stoic, hypermasculine, or emotionally distant because that feels safer than admitting that they’re unsure or hurt. That performative toughness can create walls in a relationship. It limits real connection because there’s no room for softness or openness. Under the surface, it’s often about fear of being exposed.
7. They constantly compare themselves to other men.
Low self-worth can make a man hyperaware of how he measures up. He might compare his body, income, career, or even personality to other men in subtle or obvious ways. This comparison rarely leads to motivation. Instead, it usually fuels resentment or shame. If he’s constantly referencing what “real men” do or feeling threatened by your male friends, it could be rooted in this quiet belief that he’s falling short. That can (and usually does) destroy the connection.
8. They try to prove their worth through money or success.
When self-esteem is low, external achievement becomes the measuring stick. He might pour energy into work, gifts, or status, not just to impress you, but to convince himself that he’s valuable. While ambition isn’t a bad thing, if it’s rooted in proving something, it rarely satisfies. It can also make emotional needs feel like a threat to his image or control, which puts pressure on the relationship.
9. They get defensive over small things.
Criticism, real or imagined, can feel unbearable when someone already doubts themselves. A small suggestion might feel like an attack, and a tiny disagreement might spark a huge reaction. That defensiveness usually isn’t about ego. It’s about shame. When someone’s self-esteem is low, any perceived flaw feels like confirmation that they’re not enough, and that fear can come out as anger or retreat.
10. They sabotage good things before they get too close.
If he believes he’s not worthy of love, he might start pushing you away just when things are going well. He might pick fights, get cold, or disappear emotionally, not because he doesn’t care, but because he’s scared you’ll leave once you “see the real him.” That sort of self-sabotage is painful to witness. It can make partners feel confused or rejected, when really, it’s a defence mechanism of trying to preempt heartbreak by getting there first.
11. They have a hard time showing affection.
Sometimes, men with low self-esteem struggle to show physical or verbal affection. Not because they don’t feel it—but because they don’t believe they deserve it, or don’t want to seem “needy.” That hesitation can lead to emotional distance, even if the love is there underneath. It’s not coldness; it’s feeling unworthy of giving or receiving warmth.
12. They test your love constantly.
Whether it’s pulling away to see if you’ll chase, or stirring drama just to see if you’ll stick around, some men subconsciously test their partner’s loyalty. It’s not healthy, but it often comes from fear of abandonment. These tests create instability and often backfire. What they’re really saying is “Will you still love me if I make it hard?” However, no one should have to prove their love through chaos.
13. They act like they don’t care until it’s too late.
Men who are unsure of their worth might pretend not to care about the relationship as a form of self-protection. They’d rather act indifferent than admit how invested they actually are. However, this false distance can cause real damage. It creates confusion, resentment, and missed chances for connection. Often, regret only hits after it’s already fallen apart.
14. They’re suspicious of kindness.
If you’re loving, generous, or emotionally available, a man with low self-esteem might not trust it. He might think you’re being manipulative or assume you’ll eventually withdraw it. It’s hard for someone to believe in healthy love when they haven’t experienced much of it, or don’t believe they’re worthy of it. That suspicion can block the very connection they’re craving.
15. They put their whole identity into the relationship.
When a man doesn’t feel grounded in who he is outside of love, he might start to over-identify with being your partner. He puts all his self-worth into the relationship, and if anything feels shaky, he falls apart. That kind of dependency feels intense, but it’s also fragile. It makes the relationship carry more weight than it can hold, and as time goes on, it can smother both people.
16. They don’t believe you’ll stay, even when you try to show them.
No matter how consistent, caring, or loyal you are, a man with low self-esteem might never fully believe you’ll stay. He might expect you to leave, cheat, or stop loving him, and treat the relationship accordingly. This belief often becomes a self-fulfilling prophecy, but it’s not about you. It’s about his own sense of worth, and unless that changes, no amount of love from you will feel safe enough for him to fully receive.
