raquelplankI don’t think I am bringing some novel idea to light. Lying is one of the most destructive forces in any relationship. Whether it’s a “harmless” white lie or a full-blown deception, the impact on trust, intimacy, and emotional security can be devastating. Recently, I posted about ways to rebuild trust once it has been broken. As a relationship consultant, I’ve seen countless couples struggle with the aftermath of lies, both big and small. What’s surprising, though, is not the fact that people lie—but why they do it. The reasons behind lying in relationships are complex, often rooted in deep-seated insecurities, fears, and unmet needs. Let’s dive into the uncomfortable truths that most people don’t want to admit about why lying is so rampant in relationships today.
The Comforting Illusion of Lies
One of the primary reasons people lie in relationships is to create a comforting illusion—for themselves or their partners. This is particularly true in the early stages of dating. The desire to be liked, accepted, or seen as “perfect” can drive individuals to fabricate or omit details about their past, present, or future intentions. For instance, someone may lie about their income, interests, or even their relationship history just to appear more desirable. We’ve all been there. A first date seems a bit too soon to unload all your family drama and which SSRIs you are currently on. However, many keep up the charade beyond the first date.
But why do we feel the need to curate these false personas? The answer lies in the deeply ingrained societal pressures to be perfect. We’re bombarded by images of “ideal” relationships carefully curated on social media, in movies, and even among our friends. The pressure to measure up can be overwhelming, and lying becomes an easy way to maintain the illusion that everything is flawless—even if it’s not.
Yet, when the truth eventually comes out (and it almost always does), the consequences can be far more damaging than the original flaw the lie was meant to conceal. The lie reveals a lack of authenticity, and once the veil of deception is lifted, the entire foundation of the relationship is called into question.
Story time: Nathan and Christine
A few years ago I was contacted by an old friend, let’s call him Nathan. Names have been changed to protect privacy. We had briefly dated in our teens. When I say briefly I mean about two months. I had not seen or spoken to Nathan in twenty years. He felt comfortable talking to me about his relationship with his wife. Apparently, he had been dishonest about his spending of household funds on video games. I reminded him that trust can be broken in a moment but it would take time for her to trust him again. He wouldn’t need to just tell the truth but he would need to be radically honest about everything as he attempted to earn her trust back.
His wife, Christine, was already skeptical and distrusting of Nathan, due to his past actions. However, when she found out he was talking to me about their relationship, she was livid. She felt like her trust had been broken once again. Nathan. in an attempt to diffuse her anger, decided to lie and tell her that I was a sex therapist. This was long before I became a relationship consultant. I have never been nor claimed to be a sex therapist. It does not make sense to me why he would choose that lie of all lies to “diffuse” her anger. And just as you might imagine. it made things much worse.
The point of telling you the story of Nathan and Christine is to show how damaging little lies and big lies can be. Nathan had the opportunity to be honest with his wife and chose to lie to her instead. He may have been trying to prevent further confrontation in the moment but he made it worse for himself and his relationship by lying.
Fear of Rejection: The Silent Saboteur
Another significant reason people lie in their relationships is fear—fear of rejection, abandonment, or judgment. When someone believes that their truth may cause their partner to leave or think less of them, lying becomes a defense mechanism. Instead of facing potential criticism or disappointment, they opt to tell their partner what they want to hear.
For instance, someone may lie about their feelings, their past mistakes, or even their emotional needs. They might pretend to be happy when they’re not, claim to be “over” an issue that’s still festering inside, or downplay their own desires to keep the peace. In the short term, these lies may prevent conflict, but in the long run, they erode trust and intimacy.
Lies told out of fear can create a vicious cycle. The more someone lies, the more distant they feel from their partner, which can increase the fear of being found out. Eventually, the relationship becomes a web of deception that’s nearly impossible to untangle.
The Desire for Control
Lies are often a tool for control. Whether consciously or subconsciously, some individuals use deception to manipulate the dynamics of the relationship. For example, a partner may lie about their whereabouts, who they’re communicating with, or what they’ve been doing to maintain control over how they’re perceived.
In some cases, the lie is a way to retain power in the relationship. If one partner feels insecure or threatened, they might lie to ensure that they have the upper hand. This form of deception is particularly toxic because it’s rooted in a need for dominance rather than a desire to protect the relationship.
Control-based lies are typically more calculated and intentional, making them harder to forgive when discovered. They signify a fundamental lack of respect for the other person’s autonomy and trust, and often point to deeper issues of insecurity, jealousy, or emotional manipulation.
Avoiding Conflict: The Myth of the White Lie
It’s often said that white lies are harmless—that they’re meant to protect the other person from unnecessary pain or conflict. But as a relationship consultant, I’ve seen firsthand that this is a dangerous myth. Even small lies can accumulate over time, creating cracks in the foundation of trust that are difficult to repair.
When someone lies to avoid conflict, they are essentially prioritizing short-term comfort over long-term health. For instance, lying about whether you’re upset with your partner, whether you’re still attracted to them, or how you truly feel about an issue might spare you an argument today. But it also means you’re not addressing the root of the problem, which will inevitably resurface later—often in a more damaging way.
Avoiding conflict through lying is also a form of emotional dishonesty. It signals that one or both partners are not comfortable with vulnerability, which is essential for a deep, meaningful relationship. By refusing to confront the truth head-on, couples miss the opportunity to work through their issues, grow together, and strengthen their bond.
The Role of Insecurity
Insecurity is perhaps one of the biggest driving forces behind lies in relationships. When people feel inadequate or unworthy, they are more likely to lie in an attempt to cover up these feelings. Whether it’s lying about their appearance, their achievements, or even their feelings for their partner, insecurity fuels a need to hide the parts of ourselves we fear aren’t good enough.
The tragic irony is that these lies only serve to deepen the insecurity. The more someone lies to cover up their perceived flaws, the more disconnected they feel from their true self—and their partner. Over time, the relationship becomes a battleground of insecurity, with both partners feeling unsure of what’s real and what’s been fabricated.
The Path to Healing: Rebuilding Trust After Lies
If you’ve lied in your relationship, or been lied to, you might be wondering if there’s any hope for healing. The truth is, while rebuilding trust after lies is difficult, it’s not impossible. The key is a commitment to radical honesty and vulnerability. Both partners must be willing to confront the uncomfortable truths in their relationship and work through them together.
This process often requires professional help. As a relationship consultant, I’ve guided many couples through the painful but necessary process of rebuilding trust after deception. It requires time, patience, and a deep commitment to personal and relational growth. If you or your partner are struggling to rebuild trust, I can help.
