Healthy vs Unhealthy Relationships: Green Flags, Red Flags and the Difference
Healthy vs unhealthy relationships differ in respect, freedom, and safety. This free PDF guide helps you recognize supportive patterns, controlling behavior, and reasons to seek help.

About this tool
Healthy vs unhealthy relationships differ in whether you feel respected, safe, and free to make your own choices. This printable guide compares everyday signs so you can describe what is happening and consider what support you need. Every relationship has ups and downs, and even good ones have rough patches. Look at the patterns underneath conflict: whether there is respect, trust, honesty, and room for both people to be themselves. This guide lays out those patterns side by side so you can step back and see your relationship more clearly.
Healthy relationships are built on mutual respect, trust, good communication, and support for each other's independence. Partners can disagree, repair, and keep their own friendships, interests, and sense of self. Unhealthy relationships drift the other way: toward control, contempt, dishonesty, walking on eggshells, and one person's needs consistently overriding the other's. These are sometimes called red flags, while the positive signs are called green flags.
It helps to think in terms of overall patterns rather than isolated incidents. A single bad argument does not make a relationship unhealthy, and a single sweet gesture does not make it healthy. Look at how the two of you treat each other most of the time, especially during stress and disagreement, which is where character shows.
If you recognize a lot of the unhealthy signs, that is worth taking seriously. Some unhealthy patterns can improve with effort, honesty, and sometimes couples therapy. But when control, fear, or any form of abuse is present, the priority shifts from improving the relationship to staying safe. The resources noted below can help.
Research by psychologist John Gottman identified four communication patterns that reliably predict relationship breakdown: criticism, contempt, defensiveness, and stonewalling, sometimes called the four horsemen. In long term studies following married couples over several years, these patterns, especially contempt, were among the strongest predictors of divorce. Naming these patterns is often the first step in noticing them in your own relationship, and the Four Horsemen Worksheet (Gottman) on this site walks through each one with concrete examples.
The way you learned to relate to caregivers early in life often shapes how you handle closeness, conflict, and reassurance as an adult, a pattern researchers call attachment style. Someone with a more anxious attachment style may read distance as rejection, while someone with a more avoidant style may pull back when a partner wants more closeness. Neither pattern makes a relationship unhealthy on its own, but understanding your Attachment Styles can help you tell the difference between a real red flag and a pattern that reflects your own history.
Unhealthy patterns that cross into abuse deserve attention even when there are no visible injuries. The Centers for Disease Control and Prevention includes psychological aggression in its definition of intimate partner violence: communication intended to cause emotional harm or exert control. Its guidance also recognizes physical violence, sexual violence, and stalking. This is why noticing controlling behavior matters even when you are unsure which label fits. You can seek support without proving that your experience matches every example on this page.
If you have worked through this guide and most of what you circled falls on the unhealthy side, that is information worth acting on, not a reason for shame. Many people find it helpful to talk it through with a therapist who specializes in relationships, who can help sort out what is fixable, what is a dealbreaker, and what to do next. If fear or safety is part of the picture, a domestic violence advocate can help you think through your options confidentially before you decide anything.
Use the completed guide as a record of concerns you want to discuss, rather than a relationship score or a diagnosis of either person. If it is safe to write things down, describe what happened, how you responded, and whether your boundary was respected afterward. An apology is useful context, but look for changes in behavior before assuming the concern has been resolved. The Attachment Style Test can support reflection on closeness and reassurance; it cannot determine whether someone is abusive or whether you should stay.
If you are afraid of retaliation, seek individual support before trying a shared worksheet or a joint counseling appointment. The National Domestic Violence Hotline advises against couples counseling in abusive relationships because disclosures can create additional risk. Psychology.com’s therapist directory can help you find individual support for relationship concerns. The tools hub also offers exercises for communication and reflection when practicing them feels safe.

Healthy vs Unhealthy Relationships FAQ
What makes a relationship healthy?
Mutual respect, trust, honest communication, support for each other's independence, and the ability to disagree and repair. You feel safe being yourself. In everyday terms, you can express a preference, keep meaningful friendships, and say that something hurt without being threatened. Use the guide to identify concrete examples of respect and repair in the relationship you are considering.
What are red flags in a relationship?
Constant criticism, controlling behavior, ignored boundaries, jealousy framed as love, dishonesty or gaslighting, isolation from others, and any fear, threats, or abuse. Notice how the behavior affects your freedom and sense of safety. You do not need to wait for physical injury or collect a particular number of warning signs before talking privately with someone who can help.
Can an unhealthy relationship become healthy?
Some unhealthy patterns can improve with honesty, effort, and often couples therapy. But when control, fear, or abuse is present, safety comes first, not fixing the relationship. Look for accountability and sustained changes in behavior. If you fear retaliation for speaking honestly, seek individual support first. The National Domestic Violence Hotline advises against couples counseling when abuse is present.
What if I'm scared of my partner?
Feeling afraid is a serious red flag. In the US, you can call the National Domestic Violence Hotline at 1-800-799-7233 any time, confidentially. You deserve support and safety. You can ask an advocate to help you consider options without deciding immediately whether to leave. If discussing this worksheet with your partner could increase danger, seek private support before sharing it.
How many red flags mean a relationship is unhealthy?
There is no fixed number. What matters more is the pattern: are red flags occasional and improving, or frequent and getting worse. A relationship with several serious red flags from the list above, especially fear, control, or any form of abuse, is worth taking seriously regardless of how many green flags also exist.
Is jealousy ever normal in a relationship?
Mild jealousy that you can name and talk through openly is common and not automatically a red flag. It becomes unhealthy when it turns into monitoring, controlling who your partner sees, or being framed as proof of love. The difference is whether jealousy leads to open conversation or to control.
