Spend ten minutes reading dating advice online and you might conclude that everyone is a walking red flag.
He’s close to his mother. Red flag.
She takes three hours to text back. Red flag.
He still has a photograph with his ex somewhere on Instagram. Apparently, we need to launch an investigation.
Meanwhile, someone who wants to know where you are every minute of the day gets described as “protective.”
We need to sort this out.
When we use red flag to describe everything we dislike, we make it harder to distinguish ordinary differences from behavior that deserves serious attention.
As a matchmaker and dating coach, I want singles to recognize both: the warning signs they shouldn’t explain away and the perfectly reasonable people they might be dismissing too quickly.
We also need to talk about green flags. Knowing what a healthy relationship looks like is just as useful as knowing what to avoid.
The goal is to see people clearly enough to make better decisions-not to find someone who has never done anything remotely annoying. Good luck with that search.
Why We’re So Quick to Spot Red Flags
There are understandable reasons we pay attention to what could go wrong.
In six studies involving more than 6,500 people, Peter Jonason and colleagues found that people generally gave potential partners’ negative qualities more weight than their positive ones, particularly when considering a long-term relationship.
That can help protect us from unsuitable partners. It can also make us quick to reject.
Then there’s “the ick”: that sudden loss of attraction over something that may be relatively minor.
A 2025 study by Collisson, Saunders, and Yin found that participants reported roughly ten icks across their dating histories, and 42% said they had stopped seeing someone because of one. The researchers also found associations between aspects of the ick and traits including disgust sensitivity, perfectionism, and narcissism.
That doesn’t mean everyone who gets turned off by something is a narcissist. It does suggest that our reactions can tell us something about our own expectations, rather than providing a reliable assessment of the person across the table.
Our relationship history can influence those reactions, too.
If you’ve been hurt before, you may become especially alert to anything that resembles the experience. That deserves compassion. It also deserves reflection, because something that reminds you of the past isn’t necessarily evidence that the past is repeating itself.
There’s another complication: research by Jonason and colleagues has linked lower self-esteem or greater loneliness with more willingness to accept potential partners with deal breakers.
So it’s possible to do both: reject someone over a small detail while making excuses for someone whose behavior genuinely concerns you.
That’s why learning to evaluate dating experiences matters.
Perceived Red Flags: When Something Needs Context
A perceived red flag is something that makes you uneasy but doesn’t, on its own, establish how someone will treat you.
It may reflect a difference in communication, life experience, personality, or expectations.
Here are some examples—and what would make me pay closer attention.
| The perceived “red flag” | What it could mean | What deserves a closer look |
|---|---|---|
| They’re slow to text back. | They have a demanding job, communicate differently, or prefer talking in person. | They’re also vague about plans, repeatedly disappear, or leave you uncertain about their intentions. |
| They’re close to their family. | They value family relationships and loyalty. | They can’t make independent decisions or maintain appropriate boundaries with relatives. |
| They’re friendly with an ex. | They co-parent, ended things amicably, or have established a friendship. | They hide the contact, mislead you, or allow that relationship to repeatedly disrupt yours. |
| They’re nervous on a first date. | They’re nervous. Some wonderful partners aren’t polished first-date performers. | They become rude or disrespectful toward you or the staff. |
| They’ve been to therapy or discuss their past. | They may value self-awareness and personal growth. | They use therapy language to excuse their behavior or blame everyone else. |
| You have different hobbies or tastes. | You’re two separate people with separate interests. | They belittle what you enjoy or treat their preferences as superior. |
| You don’t feel immediate fireworks. | Attraction may be subtle, uncertain, or still developing. | You continue to feel no romantic interest after spending more time together. |
| They’re divorced or have been single for years. | They have a life story you haven’t heard yet. | Every former partner is “crazy,” and they accept no responsibility for their relationship history. |
None of these situations obligates you to keep dating someone.
You can decide that a communication style or life circumstance doesn’t work for you without declaring the other person a walking disaster.
An incompatibility can be a perfectly good reason to leave. It doesn’t need to become an accusation.
A Word About “No Fireworks”
In Attached, Amir Levine and Rachel Heller discuss how people with anxious attachment patterns may experience uncertainty as exciting and overlook steadier partners because the connection feels less intense.
That’s worth considering if your most exciting relationships have also left you constantly guessing.
But calmness alone doesn’t prove compatibility, and anxiety alone doesn’t tell you why you’re feeling it.
You still need to evaluate the person and their behavior.
You also don’t have to spend months persuading yourself to feel attraction that isn’t developing.
Actual Red Flags in Dating: Behaviors to Take Seriously
Actual warning signs concern how someone treats you, handles your boundaries, and respects your independence.
Many become clearer as patterns develop. But some incidents are serious enough on their own. You don’t need to wait for a second threat, an additional act of violence, or more sexual pressure before taking action.
1. Contempt and Disrespect
Mockery. Humiliation. Talking down to you. Hostile jokes at your expense.
The Gottman Institute identifies contempt as a particularly destructive relationship behavior and describes it as its strongest predictor of divorce.
That research concerns couples; it isn’t a formula for predicting the outcome of a first date. Still, if someone is already treating you as inferior while getting to know you, pay attention.
Persistent criticism, defensiveness, and shutting down difficult conversations also deserve notice.
You’re allowed to have disagreements. You shouldn’t have to accept being demeaned.
2. Pushing Past Your “No”
You say you want to move more slowly.
They sulk, argue, bargain, or make you feel guilty.
You decline a drink, physical affection, or an invitation home, and suddenly they’re trying to convince you that your decision is unreasonable.
A boundary isn’t the opening offer in a negotiation.
Their response gives you useful information about whether they respect your choices.
3. Isolation and Control
Perhaps they criticize your friends until seeing them becomes more trouble than it feels worth.
Perhaps they expect constant location updates, demand your phone password, or get angry when you make plans without them.
Research on coercive control describes restrictive and manipulative behaviors that undermine a partner’s autonomy. Survivor accounts also show that psychological abuse can emerge before major commitments such as living together or marriage.
Someone wanting a relationship with you doesn’t entitle them to take over your life.
4. Love Bombing and Pressure to Commit
Attention, compliments, and gifts can be lovely.
The concern is what accompanies them.
White Ribbon Australia includes love bombing and pressure for rapid commitment among potential early signs of coercive control. Exploratory research has also examined associations between love-bombing behavior, narcissistic traits, and self-esteem.
That doesn’t mean an enthusiastic person or a generous gift establishes manipulation.
Notice whether you have room to think, make choices, and set the pace.
“I’m excited about you” should still leave space for “I’m not ready for that yet.”
5. Hot-and-Cold Behavior
One week you’re wonderful. The next, they’re distant, punishing, or cruel-and you’re left trying to work out what you did wrong.
Everyone has busy days or periods of stress. That’s different from repeatedly alternating affection with mistreatment.
If maintaining the connection requires you to chase reassurance and manage their unpredictable reactions, pay attention.
6. Dishonesty and No Accountability
Stories change. Important details don’t add up. Every mistake somehow becomes someone else’s fault.
Untrustworthiness appears among the deal breakers identified in Jonason’s research.
You don’t need perfection. You do need enough honesty to make informed choices about the person you’re dating.
And when something goes wrong, “I got that wrong” should be available in their vocabulary.
7. Kindness That Disappears Around Other People
Watch how someone treats servers, drivers, relatives, and people they aren’t trying to impress.
Being charming to you while humiliating someone else is worth noticing.
Their treatment of other people gives you information that a carefully planned date may not.
How to Tell a False Alarm From a Real Concern
When something gives you pause, these questions can help you organize what you’re noticing.
Is It a Moment or a Pattern?
One late reply gives you limited information.
Weeks of disappearing, vague explanations, and broken plans tell you more.
Patterns and clusters of concerning behavior deserve attention. But remember: the seriousness of an incident matters, too. You don’t need repetition to justify responding to a serious violation.
Is This About Preference or Respect?
“I wish he liked hiking” is a preference.
“He makes fun of me whenever I mention hiking” concerns respect.
Different interests may be manageable. Repeated humiliation is a different problem.
What Happens When You Raise It?
If it feels safe to discuss, explain what bothered you and observe the response.
Do they listen? Ask questions? Take appropriate responsibility? Make a change?
Or do they ridicule you, blame you, or punish you for mentioning it?
You don’t need to create a test. Ordinary conversations provide information.
And you don’t owe someone a confrontation if you’re afraid of their reaction.
How Do You Feel Over Time?
Are you increasingly comfortable being yourself?
Or are you editing everything you say, constantly rereading messages, and trying to avoid another upsetting reaction?
Your physical and emotional responses deserve attention. They’re useful information, although they don’t diagnose another person or explain a situation on their own.
One additional question is worth asking yourself: Am I finding the same fatal flaw in nearly everyone I date?
If so, your expectations or protective habits may deserve a closer look. That’s useful information you can work with.
Green Flags: What Healthy Dating Can Look Like
Green flags are sometimes easier to overlook because they don’t create much drama.
Someone listens. Keeps their word. Accepts your boundary. Handles a disappointment respectfully.
It may not make a particularly dramatic group-chat story. It can make a meaningful difference to your relationship.
They Respond to Your Attempts to Connect
You mention something that happened during your day, and they engage.
They ask a question, share the moment, or show that what you said registered.
The Gottmans call these invitations “bids for connection.” In the research described by the Gottman Institute, couples who remained together six years later had turned toward bids 86% of the time, compared with 33% among couples who divorced.
Those figures aren’t a dating scorecard. They illustrate why everyday responsiveness deserves attention.
Their Words and Actions Match
They say they’ll call, and they call.
They make plans and follow through. If something changes, they communicate.
You aren’t continually trying to decode where you stand.
They Respect Your “No”
They can be disappointed without making their disappointment your punishment.
They don’t need repeated explanations before accepting your decision.
They Repair After Friction
Healthy couples still disagree. Gottman’s work emphasizes how couples manage conflict, rather than treating the mere presence of disagreement as failure.
Look for someone who can acknowledge their part, listen to yours, and help move the conversation forward.
An apology becomes more meaningful when behavior supports it.
They Leave Room for Your Life
They’re interested in you without demanding all your time.
Your friendships, hobbies, responsibilities, and independence have room to exist.
They’re Curious About You
They ask follow-up questions.
They remember what matters to you.
You feel that they’re learning who you are, rather than checking whether you fit a role they’ve already written.
You Can Relax Into Being Yourself
You don’t have to perform, monitor every word, or continually earn their approval.
That comfort is worth noticing alongside attraction, shared values, and the way they treat you.
Calm doesn’t have to mean boring. But you’re still allowed to want romantic interest as well.
Green flags are encouraging evidence-not guarantees, and never compensation for serious harm.
Where This Fits Into The R.E.A.D.Y. Method
Recognizing red and green flags takes more than memorizing a list.
It involves understanding your own patterns, communicating clearly, observing behavior, and making decisions that support the relationship you want.
That’s why we discuss these situations in The R.E.A.D.Y. Method coaching sessions.
R — Recognize
We explore your dating patterns, attachment style, and actual needs.
Which qualities draw you in? Which concerns have you minimized? Are there differences you tend to interpret as rejection or danger before you have enough information?
Recognizing your own lens helps you evaluate someone more clearly.
E — Engage
We work on communication that builds connection and helps you understand what’s happening.
That includes expressing needs, asking questions, and noticing how someone responds.
You don’t need a perfectly rehearsed speech to say something matters to you.
A — Appeal
We explore your compatibility type and how to show up with authentic confidence.
When you’re constantly trying to become the woman you think someone wants, it becomes harder to discover whether they appreciate the person you actually are.
Your preferences, personality, and boundaries need room in the relationship, too.
D — Dare
We work on creating opportunities to meet, connect, and flirt while maintaining your boundaries.
Being open to dating doesn’t require being available to every person or accepting every invitation.
You can take a chance and still make thoughtful choices.
Y — Yes
We bring it together: evaluating the person and the relationship with clarity.
What have you observed? What feels compatible? What needs more information? What are you unwilling to accept?
The goal is to make your yes a considered choice and to feel comfortable with your no.
What We Work Through in Coaching
We approach red and green flags from several directions:
- Your own lens: We look at your dating history, including concerns you may over interpret and warning signs you’ve previously explained away.
- Real dating situations: We discuss messages, date experiences, and questions that leave you uncertain, then consider practical next steps.
- Your green flags: We get specific about what healthy behavior looks like in the relationship you want.
- What you bring: We work on your own boundaries, honest communication, and ability to participate in a healthy connection.
That’s how the conversation becomes useful beyond another list saved on your phone.
See Clearly, Then Choose
You don’t need to become more suspicious of everyone you meet.
You also don’t need to explain away behavior that hurts or frightens you because someone has other appealing qualities.
Learn to recognize the difference between an ordinary human quirk, a genuine incompatibility, and treatment you won’t accept.
Notice respect and consistency when they appear.
And remember: you don’t have to prove someone is a bad person to decide they aren’t your person.
The goal is clearer judgment so you stop dismissing good possibilities over small things and stop overlooking serious problems because you want a relationship to work.
If you’d like help understanding your dating patterns and making more confident choices, schedule a conversation with me to learn more about coaching and The R.E.A.D.Y. Method.
Bring your questions, your experiences, and your “Ella, is this a red flag?” moments.
We’ll work through them together.
