After a breakup, deciding to stay friends is only the first step. The bigger challenge is working out what that friendship should actually look like. Without clear boundaries, it’s easy for old relationship habits to continue, leaving one or both of you feeling confused, emotionally dependent, or unable to move forward.
If you’re considering staying in contact, our guide on Should You Stay Friends With an Ex? (Pros, Cons & Teen-Friendly Advice) explores the wider question of when post-breakup friendship is healthy and when it isn’t. This article focuses on the practical side of making that friendship work, because healthy boundaries are often what separate a genuine friendship from an unfinished relationship.
Setting boundaries isn’t about creating rules to punish each other. It’s about making sure the friendship supports both of your wellbeing instead of quietly recreating the problems that ended the relationship.
Why Boundaries Matter After a Breakup
When a relationship ends, the emotional connection doesn’t disappear overnight.
You may still instinctively message your ex when something good or bad happens, expect them to comfort you when you’re struggling, or feel disappointed if they don’t respond in the way they used to. Those habits are completely understandable, but they can make it difficult for both of you to adjust to your new relationship as friends.
Healthy boundaries help create a clearer distinction between what belonged to the romantic relationship and what belongs to the friendship. That change can feel uncomfortable at first, but it often gives both people the space they need to heal while still treating one another with kindness and respect.
Decide Whether You’re Both Ready
Before thinking about boundaries, it’s worth asking whether you’re both emotionally ready to be friends at all.
Friendship is much more likely to work when both people have accepted that the relationship has ended and neither is hoping the friendship will eventually become a relationship again.
If one of you is still holding on to that hope, boundaries become much harder to maintain because every interaction can feel emotionally significant.
If you’re unsure whether you’re staying friends for healthy reasons, our guide on Signs You’re Staying Friends With an Ex for the Wrong Reasons can help you recognise the emotional patterns that often make friendship more difficult than it needs to be.
Accept That the Friendship Will Be Different
One of the biggest mistakes people make is trying to keep the friendship exactly the same as the relationship.
If you still message all day, rely on one another for emotional support, spend every weekend together, or expect the same level of attention as before, very little has actually changed.
Healthy post-breakup friendships usually look different.
You may speak less often, spend less time together, and become less involved in each other’s daily lives. That doesn’t necessarily mean the friendship is weaker. It simply reflects that you’re no longer partners, and your relationship has naturally changed.
Accepting those changes is often one of the most important boundaries you can set.
Be Clear About Communication
You don’t need strict rules about how often you should talk, but it helps if both people have similar expectations.
For example, consider whether you’re comfortable:
- messaging every day
- calling one another regularly
- discussing new relationships
- contacting each other late at night
- expecting immediate replies
The answers will be different for everyone.
What’s important is that your communication feels comfortable rather than emotionally demanding. If conversations regularly leave you feeling anxious, disappointed, or hopeful that the relationship might restart, it may be worth reducing contact until your feelings become less intense.
Respect Each Other’s Independence
Healthy friendships allow both people to grow independently.
That means giving each other the freedom to build new friendships, develop new interests, and eventually enter new relationships without feeling guilty or responsible for the other person’s emotions.
One useful question to ask yourself is:
“Am I happy for them to build a life that doesn’t revolve around me?”
If the honest answer is no, that’s not something to feel ashamed of. It simply suggests your feelings may still be changing, and some additional space could help.
Our guide on When Staying Friends With an Ex Works explains why emotional independence is one of the strongest signs that a post-breakup friendship has a healthy foundation.
Boundaries Should Protect Both People
It’s easy to think of boundaries as something you set for yourself, but healthy boundaries protect everyone involved.
For example, if one person begins relying on the other for constant reassurance, emotional support, or relationship advice, the friendship can quickly become unbalanced.
Likewise, if either of you starts feeling responsible for managing the other’s emotions, it’s often a sign that old relationship patterns are returning.
Good boundaries create clarity.
Both people understand where they stand, what they can reasonably expect, and what has changed since the relationship ended.
Don’t Ignore Your Own Feelings
Boundaries aren’t something you set once and forget about.
As time passes, your emotions may change. A friendship that felt comfortable a few months ago may begin to feel emotionally draining, or you might realise you’re still hoping for reconciliation despite your best intentions.
Checking in with yourself regularly can help you notice those changes before they become overwhelming.
If maintaining the friendship consistently leaves you feeling anxious, hurt, or unable to move forward, it’s okay to step back and rethink what you need.
Changing your boundaries isn’t a sign that you’ve failed.
Sometimes it’s simply a sign that you’ve learned more about what helps you heal.
What Happens When One of You Starts Dating Someone Else?
One of the biggest tests of any friendship with an ex is how it changes when new relationships become part of the picture.
At some point, one of you may meet someone new. If your friendship has healthy boundaries, that change will probably feel manageable, even if it’s slightly uncomfortable at first. But if the friendship still depends on emotional closeness that belongs in a romantic relationship, new partners can quickly expose problems that were already there.
It’s worth asking yourself whether you could genuinely respect your ex’s new relationship without feeling pushed aside or competing for their attention. Equally, think about whether a future partner would feel comfortable with the way your friendship currently works.
Healthy friendships don’t require secrecy, emotional exclusivity, or divided loyalties. They leave room for both people to build new relationships without creating unnecessary confusion or tension.
What If Your Ex Doesn’t Respect Your Boundaries?
Setting boundaries only works if they’re respected.
Sometimes an ex may continue messaging constantly, expect emotional support, ignore requests for space, or behave as though the relationship never really ended. Even if those actions aren’t intended to be hurtful, they can make it much harder for both of you to move forward.
If this happens, it’s okay to repeat your boundaries calmly and consistently. You don’t need to argue or justify every decision. Simply explaining what you need and following through with those boundaries is often enough.
If your ex repeatedly ignores them, it may be a sign that the friendship isn’t healthy at this stage. Respect is one of the foundations of any friendship, and boundaries only work when both people are willing to honour them.
It’s Okay to Change Your Mind
Some people worry that deciding to stay friends means they’ve committed to that decision forever.
You haven’t.
Your feelings may change as you continue to heal. What feels manageable today may feel emotionally exhausting in a few months, or a friendship that initially seemed impossible may become much easier after enough time has passed.
Giving yourself permission to reassess isn’t inconsistency—it’s self-awareness.
Healthy boundaries should reflect your current emotional needs, not a promise you made immediately after the breakup.
When Distance Becomes the Healthiest Boundary
Sometimes the healthiest boundary isn’t changing how the friendship works—it’s stepping away from it altogether.
If you repeatedly find yourself feeling anxious after conversations, struggling to accept the breakup, or noticing that the friendship is preventing you from rebuilding your confidence, some time apart may be the kindest decision you can make for yourself.
Creating distance isn’t about blaming your ex or pretending the relationship didn’t matter. It’s about recognising that healing sometimes requires more space than friendship can provide.

When to Seek Extra Support
If you’re finding it difficult to maintain healthy boundaries, your emotions are affecting your confidence or daily life, or the friendship is leaving you feeling constantly anxious or overwhelmed, talking to someone you trust can help.
That might be a parent, trusted adult, teacher, counsellor, therapist, or another supportive person. They can help you understand what’s happening, think through your options, and support you in making decisions that protect your wellbeing.
Asking for help isn’t a sign that you’ve handled the breakup badly. Sometimes it’s simply easier to see things clearly when you don’t have to work through them on your own.
Healthy Boundaries Create Healthier Friendships
If you decide to stay friends with an ex, boundaries aren’t there to make the friendship feel distant or uncomfortable. They’re there to help both people move forward with clarity, respect, and emotional independence.
The healthiest post-breakup friendships usually develop because both people have accepted that the relationship has ended, communicate honestly, and respect one another’s needs without expecting the friendship to replace what they once had.
Not every breakup leads to a lasting friendship, and that’s perfectly okay. But if friendship is going to work, healthy boundaries are what allow it to grow into something that supports both people rather than keeping either of them emotionally stuck in the past.
