How to set boundaries with difficult people

Dealing with difficult people and the resulting conflict is an inevitable part of life, unfortunately. Whether it's a colleague who thrives on drama, a family member whose comments or behaviour are difficult to deal with, or a friend whose constant negativity drains your energy, navigating these relationships can feel overwhelming.

When left unchecked, these interactions can leave you feeling stressed, frustrated or resentful. However, with a better understanding of how you respond to conflict and the art of boundary setting, you can protect your well-being while engaging with others constructively.

Understanding projection

Projection is a psychological concept used to describe attributing our own thoughts, feelings or characteristics to someone else. For example, a sibling who insists you’re ‘too sensitive’ may have their own reasons for reacting in this way – but we can't know for certain what is driving another person's behaviour.

Understanding this can be helpful because someone else's comments don't automatically tell you something accurate about yourself. Their reactions may be influenced by their own experiences, feelings and perspectives, so you don't necessarily need to internalise everything they say or take their behaviour personally.

Whatever is behind another person's behaviour, you can’t control how they act, but you do have choices in how you respond.

Why boundaries are essential

Boundaries are not about shutting people out; they’re about defining what you will and won’t tolerate to maintain your emotional and mental well-being. Healthy boundaries protect your time, energy, and self-esteem, ensuring that difficult interactions don’t leave you feeling drained or resentful.

Without clear boundaries, you may find yourself accommodating others' needs at your own expense. For example, you might always say ‘yes’ to a friend’s requests even when it inconveniences you, or tolerate a colleague venting excessively about their problems during your work hours.

Over time, this may leave you feeling frustrated, resentful or drained.

Practical strategies

Give these points below a try to help maintain your emotional well-being. Like anything new, these strategies will likely take some practice and possibly feel uncomfortable initially, particularly if you’re used to being a people pleaser and putting everyone else first!

However, stay consistent, and they may start to feel easier and more familiar over time.

1. Don’t engage in their drama

When someone repeatedly tries to draw you into arguments, gossip or emotionally charged conversations, resist the urge to participate and try to stay neutral. If the conversation keeps veering into negative or unhelpful territory, politely steer it back or excuse yourself.

For instance, if your mother is constantly complaining, you could acknowledge what she's feeling by saying that you hear that she’s frustrated, angry, or sad (whatever the emotion she is expressing). You might then ask whether there is anything she would like to do about the situation.

This can shift the conversation without making you responsible for fixing the problem or dismissing how she feels.

2. Don’t automatically take their reaction personally

When someone reacts negatively to something you've said or done, it can be tempting to react defensively. Instead, pause to take a step back and consider whether their response necessarily says something about you.

So, if a family member accuses you of being selfish after you’ve set a boundary, their reaction doesn't automatically mean that setting the boundary was wrong.

A simple response such as, ‘I’m sorry this is difficult for you, yet I’m sure you can understand that I need to do what’s best for me’, can reinforce your boundary without escalating the conflict.

3. Set and communicate boundaries clearly

Boundaries need to be clear and communicated calmly to be most effective. For example, with a colleague who frequently interrupts your focus with non-urgent requests, you could let them know that you will be happy to help, but that you are working on something that requires your full focus right now and set a pre-arranged time to discuss later.

Consistency is key to maintaining your boundaries. Being consistent can make it easier for other people to understand where your boundaries are and what they can expect from you.

4. Use the power of silence

Sometimes, the best response to difficult behaviour is no response at all. If someone is trying to provoke you, silence may help you avoid escalating the situation.

This doesn’t mean ignoring them entirely but choosing not to continue an interaction that is becoming unproductive.

5. Protect your energy

If interactions with certain people consistently leave you feeling drained, it may be time to limit your exposure to them. This could mean reducing the frequency of interactions or keeping conversations brief and focused.

When avoidance isn’t possible, such as family gatherings or work colleagues, think about what might help you recharge afterwards. Whether it’s a walk, journaling, or meditation, prioritising your well-being can give you some space following challenging encounters.

6. Stay grounded in your values

When people attempt to undermine your confidence or challenge your integrity, stay grounded in your core values to avoid being swayed by their negativity.

For example, if someone makes snide comments on your decision to prioritise your work-life balance, remind yourself why it’s important to you so you can stand firm in your choice. Your values act as an anchor, keeping you steady in turbulent interactions.

Seek support when needed

Sometimes, dealing with conflict and difficult people takes more than individual effort. Talking things through with someone you trust can provide another perspective, and different forms of professional support may be appropriate depending on what you're experiencing.

Coaching can help you explore practical ways to navigate everyday conflict, communicate your needs and strengthen your boundaries. A coach can work with you to identify recurring challenges, consider how you respond to difficult interactions and explore what you might want to do differently.

Where a relationship is causing significant emotional distress or involves longstanding difficulties, therapeutic or other appropriate professional support may be more suitable.

If a situation involves abuse, coercive control, threats or concerns about your safety, the priority should be seeking appropriate specialist support rather than trying to manage the situation through boundaries or communication alone.

Maintaining your peace isn’t selfish; it’s a necessary act of self-respect. You can’t control how another person behaves, but you can consider how you respond, what boundaries you need and when it may be better to step away from an interaction.
