Key idea: when considering horizontal and vertical relationships, do not look for an exact 50–50 division of every task. Look at whether both people retain dignity, a voice, autonomy and a genuine ability to influence what happens. Inequality becomes concerning when one person routinely decides and the other gives in through fear, dependency or concern about the consequences.
Article contents
Horizontal and vertical relationships describe how influence, responsibility and decision-making are distributed within a relationship. The idea may sound simple, but it needs to be used carefully. A couple can have different roles and remain equitable, while another couple may appear equal yet organise daily life around fear or control.
It is therefore not enough to ask who earns more, who speaks most or who organises the household. It is more useful to notice whether both people can express needs, set boundaries, maintain relationships of their own, take part in important decisions and say ‘no’ without being punished, threatened or subjected to silence intended to make them comply.
In this article, I explain what these ideas mean, how they can appear in couples, families, friendships and workplaces, and which questions may help you reflect on a relationship. The purpose is not to label somebody after one argument. It is to understand patterns and distinguish a practical difference in roles from an imbalance that reduces somebody’s freedom.
The language of horizontal and vertical relationships is an accessible way of discussing interpersonal power and influence. These are not clinical diagnoses or categories found in diagnostic manuals. They can provide a useful map for thinking about a relationship, but they cannot determine by themselves whether a couple is healthy or harmful.
What are horizontal and vertical relationships?
Power exists in every relationship. Here, power does not necessarily mean ordering somebody about. It means being able to affect what happens: to suggest, refuse, negotiate, access resources, make decisions about your own body and participate in matters that affect your shared life.
What is a horizontal relationship?
A horizontal relationship is one in which both people are recognised as having equal worth and legitimacy, even when their abilities, incomes, responsibilities or needs differ. Influence moves in both directions. Important decisions are discussed, and neither person is reduced to the role of always obeying, always caring or always adapting.
Being horizontal does not mean agreeing about everything. A healthy relationship can include anger, disagreement and periods of considerable practical imbalance. During an illness, for example, one person may need to take on more tasks and make urgent decisions. What matters is that the asymmetry has an understandable reason, does not remove anybody’s dignity and can be reviewed when circumstances change.
What is a vertical relationship?
A vertical relationship involves an established difference in authority or influence. One person may have greater decision-making power because of their role, experience, financial position or the other person’s dependency. Some verticality may be necessary in particular situations, such as between an adult and a child, between a professional and someone seeking guidance, or between a carer and someone who temporarily needs substantial help.
The problem begins when that difference is no longer limited to a particular role and becomes the permanent structure of the relationship. One person decides what is bought, who the other person sees, when sex takes place, how children are raised or which emotions are acceptable. The other person learns that disagreeing carries a cost.
Differences between horizontal and vertical relationships
The differences between horizontal and vertical relationships are easier to understand through recurring patterns than through isolated incidents. The comparison below uses separate cards rather than a conventional table so that it remains clear on a mobile phone. These are prompts, not rigid rules.
Voice and decisions
Autonomy
Money and resources
Intimacy and consent
Conflict and repair
Privacy and support network
A dyadic study involving 879 couples found an important nuance: relationship quality did not simply depend on both partners possessing a mathematically identical amount of power. It was associated with each partner experiencing a sense of influence. Clinically, this supports a useful distinction: couples do not need mechanical equality, but both people need agency.
Not every asymmetry is abuse: the pattern matters
At times, one person may lead and the other may trust their judgement. This may happen because one knows more about a particular issue, because there is an emergency or because the couple have divided certain responsibilities. One person completing the tax return or managing medical appointments does not automatically make the relationship vertical or harmful.
When distinguishing horizontal and vertical relationships, four features can help you consider what is happening: duration, consent, whether the arrangement can be reviewed and the consequences of disagreeing. A practical difference in roles is usually specific and negotiable. A pattern of domination spreads across different areas and gradually reduces the other person’s freedom.
Practical difference
One person temporarily assumes more responsibility because of experience, health or circumstances. The other retains information, a voice and the ability to review the arrangement.
Persistent imbalance
One person’s needs nearly always carry more weight. The other continually adapts, builds resentment or feels that their judgement does not count.
Control or abuse
There is fear, threats, isolation, monitoring, sexual coercion, financial control or punishment designed to make somebody submit. Safety becomes the priority.
An example: if one person manages the money because they are more confident with finances, but both partners understand the accounts, have access to resources and review important decisions together, there is a difference in roles. If that responsibility is used to hide information, prevent essential spending or threaten to leave the other person without money, something very different is happening.
Where power appears in everyday life
Grand statements about equality matter less than small, repeated actions. Looking at horizontal and vertical relationships through everyday areas can help someone move from ‘something does not feel right’ to a clearer description that can be understood and addressed.
Money
Who understands the accounts, who can spend, what happens if somebody wants to work, and whether debts and financial decisions are shared.
Time and caring
Who rests, who anticipates family needs, who gives up their plans and whether invisible emotional and organisational labour can be renegotiated.
Family and friends
Whether both people maintain connections of their own, or one person disparages, restricts or turns every outside relationship into a conflict.
Mobile phones and privacy
Sharing a password can be voluntary. Demanding it, reading conversations or imposing location tracking is not the same as trust.
Sexuality and affection
Whether consent can change, whether discomfort is heard, and whether affection or sex is used as a bargaining tool or punishment.
Future decisions
Housing, children, work, health or moving home: who can introduce alternatives and what happens when the partners’ plans differ.
Relationship self-check: questions to consider
This self-check about horizontal and vertical relationships does not replace a professional assessment and does not produce a diagnostic score. Use the questions to notice patterns, considering what usually happens rather than focusing only on the best or worst day in the relationship.
- Can I say no without fearing punishment, threats, humiliation or days of silence?
- Does my opinion genuinely affect important decisions, or am I only listened to as a courtesy?
- Do I have reasonable access to the money, information and resources that affect my life?
- Can I maintain friendships, family connections, interests and time of my own without paying an emotional price?
- Is my privacy respected, or must I constantly prove that I am not hiding anything?
- Can I change my mind or stop sexual contact without pressure, guilt or intimidating anger?
- Can responsibilities and caring work be renegotiated when one person becomes overloaded?
- Do both people apologise and repair harm, or does blame repeatedly fall on the same person?
- Do my needs matter even when they are inconvenient for the other person?
- Can I discuss a concern without routinely ending up doubting my memory or judgement?
- Are our agreements explicit and open to review, or do they operate as obligations I never chose?
- Do I ever change my behaviour mainly because I am afraid of how my partner will react?
One concerning answer does not define the whole relationship. However, repeated loss of freedom, fear, monitoring, isolation or coercion should not be reduced to ‘we need to communicate better’. Safety and appropriate support need to be considered.
Dependency, independence and interdependence
Discussions of horizontal and vertical relationships can make complete independence sound like the ideal. In reality, people need one another. Asking for support, sharing resources or going through a period of greater dependency does not make a relationship unhealthy.
A healthier alternative is often interdependence: I can rely on you without losing myself; I can care for you without becoming responsible for all of your emotions; and we can build a shared life without either person giving up their identity. Giving and receiving do not need to look identical every day, but care and influence should be able to move in both directions over time.
Sick leave, illness, the arrival of a baby or a family crisis can radically change the balance of responsibilities. What protects the relationship is acknowledging the burden, maintaining transparency, appreciating care and reviewing the arrangement when possible — not pretending that both people are contributing exactly the same amount.
How to build a more horizontal relationship
If both people are safe and can speak freely, patterns associated with horizontal and vertical relationships may be changed. The aim is not to win an argument about who has more power. It is to create conditions in which both people’s needs have genuine consequences.
- Look at specific events. Replace ‘you are controlling’ with a description: ‘the last three financial decisions were made without me having the information’.
- Choose one area. Trying to change money, sex, extended family and domestic responsibilities in one conversation is likely to overwhelm both people. Begin with something clearly defined.
- Turn needs into observable agreements. For example, review the accounts once a month, alternate a responsibility or ask before accepting a commitment that affects both partners.
- Protect autonomy. Keep time, resources and relationships of your own. Closeness does not require unlimited access to every conversation, thought or personal space.
- Review the effect. An agreement may appear fair on paper and still not work. After a few weeks, ask what has changed and who continues to carry most of the burden.
- Practise repair. Acknowledge the effect of a behaviour, apologise without immediately defending it and act differently. This helps rebuild safety and credibility.
Phrases that may help you begin the conversation
These sentences are not magic formulas, but they can help you speak from a specific need. Use them only when you can express yourself safely.
‘We do not have to think alike, but I do need to be involved before the decision has already been made.’
‘You managing this area does not mean I should be left without information or a meaningful say.’
‘My mobile phone is a private space. We can discuss your insecurity without making monitoring a condition of the relationship.’
‘I would like us to review how rest is shared, not only the tasks that are easy to see.’
If every attempt to talk leads to intimidation, threats, destruction of property, extreme blame or increased monitoring, the problem is not a failure to find gentler words. Seek individual and specialist advice.
When imbalance may be coercive control or abuse
The distinction between horizontal and vertical relationships must never minimise coercive control or abuse. The World Health Organization includes psychological harm, sexual coercion and controlling behaviours within intimate partner violence. These can occur without physical assault. Financial control, isolation, threats, digital monitoring or causing somebody to change their behaviour through fear are signs that need to be taken seriously.
If you are afraid, prioritise your safety
If there is immediate danger in Spain, call 112. Spain’s official 016 service provides women with information, legal advice and immediate psychosocial support relating to all forms of violence. It is also available through WhatsApp on 600 000 016, online chat and email at 016-online@igualdad.gob.es.
You do not need to have decided to report the abuse or end the relationship before asking for information. If you believe your device may be monitored, use a safe phone or computer where possible. Avoid making sudden technological changes that could increase risk without specialist advice.
When coercive control or abuse is present, a joint conversation or couples therapy is not usually the appropriate first step. The controlling partner’s presence can prevent free disclosure, and information discussed in a session could lead to retaliation. An individual assessment of safety and available support should come first.
How couples therapy may help
Couples therapy may help partners explore horizontal and vertical relationships when the relationship is distressed, both people remain free to speak and each is willing to examine their own contribution. The therapist’s role is not to decide who is right. It is to make the cycles maintaining the problem visible and help the couple create safer, more realistic agreements.
Therapy may help a couple to:
- Identify who holds influence in each area and which needs have been overlooked.
- Distinguish a request, a boundary and an attempt to control.
- Improve listening without turning each disagreement into a threat to the relationship.
- Share visible and invisible responsibilities more consciously.
- Restore autonomy, intimacy and the ability to repair harm.
- Consider whether joint therapy is suitable or whether an individual need requires separate support.
You may also find it helpful to read about communication and conflict in couples and how attachment styles can affect relationships. These factors may help explain insecurity or repeated patterns, but they never excuse coercion, humiliation or abuse.
At Ocnos Psychology Clinic in Palmones (Los Barrios), we work with individuals and couples from across the Campo de Gibraltar. An initial assessment can help clarify what is happening and whether joint work, individual therapy or referral to a specialist service would be most appropriate.
The value of considering horizontal and vertical relationships lies in making repeated patterns visible. Horizontal and vertical relationships are not permanent identities: dynamics may change, but meaningful change requires safety, accountability and respect for each person’s autonomy.
Frequently asked questions about horizontal and vertical relationships
What are horizontal and vertical relationships?
They describe how influence is distributed. In a horizontal relationship, both people retain a voice, autonomy and a genuine ability to participate. In a vertical relationship, one person has greater authority or decision-making power. These are not diagnoses, and verticality is not harmful by definition.
Are all vertical relationships toxic?
No. Practical differences may exist because of age, knowledge, health or responsibility. They become concerning when they are permanent, cannot be reviewed and cause one person to lose freedom or comply because they fear the consequences.
Can a couple be horizontal if one partner earns more?
Yes. Relational equality does not require identical incomes. What matters is that money is not used to impose decisions, that financial information is transparent, and that both partners have security and meaningful participation in accordance with their agreements.
Is emotional dependency on a partner always unhealthy?
No. Needing support and allowing another person to care for us are part of intimacy. Healthy interdependence means that we can give and receive help without losing our identity, autonomy, relationships of our own or ability to make decisions.
How can I distinguish an unequal arrangement from control?
Consider whether the arrangement was agreed, whether both partners have information, whether it can be reviewed and what happens when somebody disagrees. Fear, monitoring, isolation, threats, sexual coercion and financial control indicate something more serious than an imperfect division of responsibilities.
Can a vertical relationship become more horizontal?
It may change when both people recognise the pattern, there is safety and the person with greater influence is willing to relinquish control and respect boundaries. When fear or abuse is present, private conversations alone are not a safe way to change the relationship; seek specialist support.
When can couples therapy help?
It may help when both people can speak freely, want to understand the problem and are willing to review their behaviour. If there is coercive control, fear or abuse, an individual safety assessment is needed first; joint therapy is not usually the appropriate starting point.
What should I do if I am afraid of my partner?
Prioritise your safety and use a safe device if you believe you are being monitored. In an immediate emergency in Spain, call 112. Women can contact the free 016 service, WhatsApp 600 000 016, the official online chat or 016-online@igualdad.gob.es.

Explore your relationship with professional support
If you struggle to make decisions without returning to the same conflict, feel that one person always adapts or want to create more equitable agreements, an assessment may help you make sense of the pattern.
If there is fear, control or abuse, seek individual or specialist support first. Do not rely on a joint session as your only safety measure.
