8 boundaries you should never cross in a relationship, according to psychology

Healthy relationships are built on mutual respect, understanding, and clear boundaries.

As someone who has had their fair share of relationship blunders, I’ve learned the importance of setting and respecting boundaries.

According to psychology, there are certain lines that should never be crossed in a relationship. And no, this doesn’t just apply to romantic relationships, but friendships and family relationships too.

The thing is, understanding these boundaries can be a game-changer. It can foster respect, understanding, and ultimately, love.

So, what are these non-negotiable boundaries?

In this article, I’m going to unveil 8 of them. These are boundaries that psychology suggests are crucial for maintaining healthy and respectful relationships.

1) Respecting personal space

Let’s be honest: having a successful relationship is impossible without embracing closeness and intimacy.

After all, relationships are all about sharing experiences, creating memories, and being there for each other, right?

But there’s a flip side to this coin.

No matter how close you are, every individual needs their own personal space — physically, emotionally, and mentally.

Think of it as a sanctuary where one can unwind, introspect, and regain their energies.

Not surprisingly, crossing this boundary isn’t just intrusive — it can be downright damaging.

It can lead to feelings of suffocation and resentment, which can eventually erode the very foundation of the relationship.

But psychology underscores the importance of personal space in maintaining healthy relationships.

It emphasizes that respecting this space is not about distancing oneself but about acknowledging and honoring individuality.

And trust me, understanding and respecting this boundary can make a world of difference in your relationships.

2) Ignoring Consent

Now, let’s talk about a word that holds immense power – consent.

Psychologists often use this term in relation to therapy and for them, consent is about agreeing to something willingly and voluntarily.

And this isn’t limited to physical aspects — it applies to emotional and mental aspects too.

Here’s the deal:

Ignoring or bypassing consent is a significant boundary violation in any relationship.

It indicates a lack of respect for the other person’s autonomy and their right to make decisions about their own lives.

Whether it’s deciding on a movie to watch, planning a vacation, or making major life decisions, seeking and respecting consent is crucial.


Because it ensures that both parties feel valued, heard, and involved.

However, it’s also important to remember that consent isn’t just a one-time thing.

It should be sought on an ongoing basis. Only then can it truly serve as the cornerstone of respect and mutual understanding in a relationship.

3) Disregarding emotional boundaries

Following on from the importance of consent, it’s crucial to recognize that emotional boundaries are just as significant as physical ones.

I know this might seem a bit surprising. After all, emotions are intangible. They can’t be seen or touched, so how can one possibly cross an emotional boundary?

Well, psychology has an answer to that as well.

Emotional boundaries are about respecting the feelings, thoughts, and experiences of others. It’s about not imposing your emotions or expectations on someone else.

  • Dismissing someone’s feelings because you don’t understand them or because they make you uncomfortable? That’s crossing an emotional boundary.
  • Using guilt or manipulation to influence someone’s feelings or decisions? That’s another violation.

It’s vital to remember that each individual has a unique emotional landscape. What might seem like an overreaction to you could be a deeply felt emotion for them.

So yes, emotional boundaries may be less visible but they’re absolutely essential to maintaining healthy relationships.

4) Violating trust and privacy

Ever felt a sense of unease when someone snoops on your personal messages or insists on knowing every single detail of your day?

This feeling stems from a violation of trust and privacy, which is a significant boundary in any relationship.

In psychology, trust is regarded as the consent. When you have trust, you believe in the integrity, character, and strength of another person.

Privacy, on the other hand, is closely tied to personal space. It means respecting the individual’s right to keep certain aspects of their life private.

So, here’s the thing:

Violating these boundaries could result in feelings of insecurity and vulnerability. It could shake the very foundation of trust and mutual respect in a relationship.

Conversely, preserving trust and privacy can strengthen the bond between individuals — fostering a sense of safety and security within the relationship.

5) Tolerating disrespectful behavior

Another fundamental requirement in every relationship is respect.

Simply put, respect means that you value the other person’s feelings, thoughts, and experiences.

But what happens when this respect is not reciprocated?

Crossing the boundary of respect can take many forms, including:

  • Continually interrupting or talking over someone
  • Making derogatory comments or jokes
  • Dismissing or invalidating someone’s feelings or experiences
  • Failing to acknowledge or appreciate the other person’s efforts

Each of these behaviors can undermine the other person’s sense of self-worth and dignity. It can lead to feelings of frustration, resentment, and even emotional pain.

On the other hand, mutual respect can nurture a sense of equality and understanding.

The best part is that such kind of respect can foster a safe space where each person feels valued and heard.

6) Allowing constant negativity

Have you ever noticed how some relationships just drain you, while others uplift you?

Well, I certainly have.

But luckily, now I realize that this has a lot to do with the level of positivity or negativity in the relationship.

Now, let’s be clear:

No relationship is perfect.

We all have our bad days, our disagreements, and our bouts of moodiness. It’s part of being human.

But when negativity becomes a constant in the relationship, that’s when it crosses a boundary.

It could be constant criticism, frequent fights, or a persistent sense of dissatisfaction. These are all signs of a negative relationship dynamic.

In either case, I’m sure about one thing:

When we allow this constant negativity, it can drain our emotional energy and rob us of the joy and fulfillment we should be getting from the relationship.

I’m not saying that you should have occasional disagreements at all costs. Not at all and they do have their own perks.

But constant negativity is a boundary that should never be crossed.

7) Overstepping financial boundaries

Imagine this:

Your friend asks you for a loan. You’re hesitant, but you lend them the money anyway. Then, it happens again. And again. Before you know it, you’re more of a bank than a friend.

Does this sound familiar?

Well, financial boundaries are often overlooked in discussions about relationships. However, psychology emphasizes its importance in maintaining healthy dynamics.

Overstepping these boundaries can take many forms. It could be

  • Borrowing money frequently without returning it
  • Making large financial decisions without consultation
  • Imposing one’s financial habits on the other.

All these actions can lead to feelings of resentment and discomfort. What’s worse, they can strain the relationship and potentially lead to conflict.

However, respecting financial boundaries can foster a sense of security and mutual respect.

That’s how each individual can maintain their financial autonomy while also cooperating on shared financial decisions.

8) Neglecting self-care and well-being

Finally, and perhaps most importantly, neglecting self-care and well-being is a boundary that should never be crossed in any relationship.

Of course, I’m not saying you have to be selfish or self-centered.

What I mean here is that you need to acknowledge the simple fact that we can’t pour from an empty cup.

As simple as it sounds.

Look, neglecting your own well-being, whether it’s physical, emotional, or mental, can lead to burnout and resentment.

It can cloud your ability to maintain healthy relationships.

But what if you could prioritize self-care?

Then you would be able to foster a sense of balance and fulfillment and, most importantly, bring your best self to every relationship and interaction.

Are you setting the right boundaries?

As we’ve explored, setting and respecting boundaries is crucial to maintaining healthy and respectful relationships.

But setting the right boundaries isn’t just knowing what lines not to cross. It also means that you understand what makes a relationship positive and fulfilling.

To help you reflect on this, here are a few pointers:

  • Open communication: Are you able to express your feelings and thoughts without fear of judgment or retaliation?
  • Shared values: Do you share common values that guide your decisions and actions in the relationship?
  • Balance: Is there a balance of give and take, where both individuals feel valued and appreciated?
  • Resilience: Does the relationship withstand challenges and disagreements without breaking down?

These factors can serve as a guide in setting the right boundaries and nurturing positive relationships.

As we navigate our relationships, let’s remember that boundaries aren’t restrictions. They’re guidelines that help us interact with respect, understanding, and love.
