Deal breakers are values in conflict, not character flaws
A deal breaker isn't necessarily about catching someone in a lie or watching them treat service workers badly. It's about discovering that the two of you want fundamentally different things from life, and neither of you will bend. You say you want stability and they say adventure is the only thing worth having. You prioritize family and they prioritize career above everything else. You need honesty and they've decided that some truths hurt more than they help. These aren't problems you can solve with better communication or more effort. They're baked into how each of you sees the world.
Most people confuse deal breakers with red flags. A red flag is someone's behaviour—they lose their temper, they're secretive, they avoid commitment. A deal breaker is someone's values. It's the slow realization that you're building toward different futures. By the time you notice it, you've often already invested time and hope, which makes the truth harder to see. The person themselves might be kind and stable and genuinely well-intentioned. They're just not aiming at the same target you are.
You only know your deal breakers when you know your values
You can't identify a deal breaker until you've actually clarified what matters to you. This sounds obvious. It's not. Most people go through relationships reacting—feeling annoyed, feeling unseen, feeling like something is off—without ever naming what they actually need. Then when a relationship ends, they tell themselves it was about the other person's flaws. Sometimes it was. Often, it was about a values collision neither of them had articulated.
Consider someone who values independence highly. They might stay in a relationship for years with someone who needs a lot of reassurance and togetherness, feeling increasingly drained without understanding why. They blame their partner for being needy. The partner feels abandoned. Neither has named the actual incompatibility: one person thrives with autonomy, the other thrives with closeness. Once you know that independence is a core value for you, you can recognize early on whether a partner's needs match yours. You can have that conversation. You can decide whether this is something you can bridge or whether it's a fundamental misalignment.
The same goes for how you approach money, family involvement, honesty, ambition, spirituality, whether you want children, how you handle conflict, what you think commitment means. You don't discover these values by thinking about them in the abstract. You discover them by paying attention to moments when you've felt truly frustrated or angry or violated in a relationship. What was actually happening underneath that feeling? What did the other person do that felt so wrong? Usually, it points directly to a value they weren't honouring in you or you weren't honouring in them.
The ones you miss are the ones you haven't named yet
People often stay in relationships that aren't working because they can't quite articulate what the problem is. There's a sense that something fundamental is off, but it looks fine on the surface. The person is kind. They're dependable. They're attractive. They want to make it work. But you find yourself withdrawing, feeling unseen, or quietly building a fantasy where someone else is in the room instead.
This happens because the values conflict is operating in the background. You might not even have words for it yet. Maybe you've always valued spontaneity but are with someone who needs structure and predictability. Maybe you need to feel admired and they're content with companionship. Maybe you believe vulnerability is essential and they believe privacy is. These misalignments don't announce themselves. They show up as a persistent unease, a sense that you're negotiating your own needs down to fit into someone else's world.
The risk is staying too long in something that's fundamentally misaligned, telling yourself that love should be enough to bridge the gap. Love is not enough. Shared values are what makes a relationship sustainable. You can love someone and still not be compatible. You can respect someone and still not share what matters most.
What to do now
Start by getting clear on your own values. Not what you think you should value. Not what your family told you to value. What actually lights you up, what makes you feel alive, what feels non-negotiable when you imagine your best life. Then look at your current relationship or the relationships you've been in. Which values are shared? Which ones are in tension?
For the ones in tension, ask yourself: Is this something we can both live with as different, or is it something that will erode the relationship over time? Some value differences don't matter much. You like hiking and they like museums. You can do both. But if one of you needs to feel like a priority in your partner's life and the other needs independence above all else, you're working against the grain of how each of you is built. That's the deal breaker territory.
If you're trying to decide whether to stay or go, clarity about values won't make the decision for you. But it will tell you what you're actually choosing. You'll know whether you're compromising on something that matters deeply or whether you're navigating a difference you can genuinely live with. That's the only way to make a choice you won't resent later.
The My Values assessment surfaces what actually matters to you, ranks it, and shows you where your current life does and doesn't match what you said you care about. It's a useful place to start.
What's the difference between a red flag and a deal breaker?
A red flag is behaviour—someone lies, gets angry easily, or avoids responsibility. A deal breaker is incompatibility in values—you want different things from life and neither of you will budge. Red flags are problems within the person. Deal breakers are problems between the two of you.
Can you compromise on deal breakers?
Not really. If something is truly a deal breaker, it means you can't live well with someone who doesn't share it. You might compromise on how you express a value or make space for both ways, but if the core value is incompatible, one or both of you will end up feeling resentful or unmet. That's how you know it's a deal breaker and not just a difference.
How do you know if a conflict is about values or just about communication?
Better communication won't fix a values clash. If you've talked openly about what matters to you and the other person still doesn't care or actively disagrees, it's values. If you haven't had that conversation yet, start there. But once both people understand what's at stake and one of you still isn't willing to prioritize it, that's when you know it's deeper than talking.
Is it possible to have too many deal breakers?
Yes. If you have a long list of inflexible requirements, you're likely protecting yourself from risk by setting impossible standards. Real deal breakers are usually a handful—the things that matter so much you genuinely cannot build a life with someone who doesn't share them. Everything else is preference, and preferences can shift or be negotiated.
