Fear of Abandonment in Polyamory: How to Stop Letting the Fear Run Your Relationships
Published May 30, 2023 | Updated August 2, 2026
There was a time when the possibility of someone leaving could completely change the way I experienced a relationship.
Nothing had to be happening.
My partner could be loving me exactly as they always had. We could be having a perfectly good day. There could be no conflict, no rupture, no indication that anything was wrong.
And still, somewhere inside me, a quiet alarm would go off:
What if this doesn't last?
Once that fear appeared, it could become difficult to stay present.
Instead of enjoying the relationship I was actually in, part of me was already preparing for the relationship to end.
I would look for signs and think about what could go wrong.
I would wonder whether someone else might become more important.
I would want reassurance because I wanted certainty that I wouldn't lose something I loved.
And sometimes, I would do something even more confusing:
I would start pulling away.
If I could convince myself that I didn't need someone, maybe losing them wouldn't hurt as much.
Looking back, I can see how much energy I spent trying to prevent an experience that hadn't actually happened.
That is one of the cruelest things about fear of abandonment.
It can pull you out of the relationship you're living and into the relationship you're afraid you're going to lose.
In polyamory, there can be even more opportunities for that fear to get activated.
Your partner can fall in love with someone new.
They can experience intense New Relationship Energy and build relationships you're not part of.
They can spend time, experience intimacy, and create memories with other people.
None of those things automatically mean they're leaving you.
But if part of you has learned that love is something you can lose at any moment, your partner's freedom to love others can bring that fear very close to the surface.
The answer isn't to convince yourself that nobody will ever leave.
It isn't to become so "secure" that loss no longer matters.
And it isn't to become less attached so you won't have as much to lose.
The deeper work is learning something much more powerful:
I can love someone deeply without abandoning myself to keep them.
Can You Practice Polyamory With Fear of Abandonment?
One of the most painful conclusions people can reach is:
Maybe I'm just not built for this.
I've had moments like that myself.
When the fear felt particularly intense, it was tempting to assume that the problem was polyamory.
But I eventually realized something much more important:
My fear of abandonment didn't begin when I became polyamorous.
Polyamory revealed it.
There were already parts of me that had learned to associate closeness with the possibility of loss.
I had already learned to look outside myself for evidence that I was wanted, valued, safe, and still connected.
Non-monogamy simply created situations where those patterns became much harder to ignore.
If polyamory brings your fear of abandonment to the surface, that doesn't automatically mean you need to leave polyamory.
It may mean you're encountering a part of yourself that wants your attention.
Research on attachment also supports an important nuance here: attachment security isn't necessarily identical across every relationship. People can experience different levels of security with different partners.
So if you feel deeply secure with one partner and intensely activated with another, that doesn't necessarily mean you're secretly incapable of secure attachment.
Why Does Polyamory Trigger Fear of Abandonment?
In monogamy, there can be an implicit story that once you've chosen each other, the relationship is the primary container for romantic love.
Polyamory challenges that assumption.
Your partner can develop another meaningful relationship without your relationship disappearing.
They can fall in love with someone new without falling out of love with you.
They can have experiences that don't include you.
They can discover parts of themselves with someone else.
And you cannot always know exactly what will happen next.
That can be uncomfortable even when everyone is behaving with care.
How Does Fear of Abandonment Lead to Controlling Behavior in Polyamory?
Fear doesn't always look like obvious clinginess.
Sometimes it looks like trying to manage the relationship so thoroughly that there is no room left for uncertainty.
You might want to know every detail about your partner's other relationships.
You might monitor changes in communication and become highly focused on how much time they're spending with another partner.
You might repeatedly ask where the relationship is going and push for commitments before you're actually ready for them.
You might compare yourself to your partner's other partners.
You might ask for reassurance over and over.
Or you might do the opposite by withdrawing and convincing yourself that you don't care.
You might tell yourself that if you don't get too attached, you can't get hurt.
These behaviors can look completely different on the surface.
But underneath them can be the same fear:
If I can control what happens, maybe I can prevent myself from being abandoned.
The problem is that relationships cannot be made completely predictable.
And trying to eliminate uncertainty can eventually create the very disconnection you're afraid of.
Can Fear of Abandonment Make You Leave a Relationship First?
This is one of the less obvious forms of abandonment fear.
You might think fear of abandonment always makes someone cling.
It doesn't.
Sometimes it makes someone disappear.
You notice yourself becoming attached.
You notice that you care.
You realize that the relationship matters to you.
And suddenly the possibility of losing it feels unbearable.
So you create distance, become harder to reach, and stop asking for what you want.
You convince yourself that you weren't that invested anyway.
Or you decide that ending things now will hurt less than waiting for someone else to end them.
This can feel like self-protection.
But sometimes you're not actually protecting yourself from heartbreak.
You're protecting yourself from the vulnerability of not knowing.
Those are different things.
How Does Fear of Abandonment Affect Polyamorous Relationships?
Another pattern I've seen repeatedly—including in myself—is turning ordinary moments into tests of whether someone is going to stay.
If they respond quickly, we're okay.
If they initiate plans, we're okay.
If they seem excited to see me, we're okay.
If they are affectionate after seeing someone else, we're okay.
If they need space, something must be wrong.
If they are distracted, maybe they're pulling away.
If they become excited about someone new, maybe I'm losing them.
The relationship starts becoming a constant stream of evidence.
You aren't simply experiencing your partner anymore.
You're evaluating them, and you're evaluating yourself through them.
That's incredibly exhausting.
It also means your sense of security becomes dependent on getting the right signals often enough.
But no partner can provide enough evidence to permanently eliminate the possibility of loss.
Eventually, something will happen that creates uncertainty again.
The deeper work is learning that uncertainty itself doesn't have to mean abandonment.
How Can Your Partner Support Your Fear of Abandonment Without Being Responsible for It?
This is one of the hardest distinctions I've had to learn.
Your partner can absolutely support you.
They can reassure you, tell you they love you, make intentional plans with you, and repair after conflict.
They can be responsive and emotionally available.
This isn't about becoming completely self-sufficient and deciding you shouldn't need anyone.
That's not security.
That's isolation hiding underneath a "healed" mask.
The deeper shift is recognizing that your partner can participate in your sense of safety without being solely responsible for creating it.
They can meet you, but they can't guarantee the future.
They can love you, but they can't guarantee that you will never experience loss.
They can reassure you, but they can't permanently convince you that you're worthy.
They can be there for you, and you can learn to be there for yourself, too.
What Are You Actually Afraid Will Happen If Your Partner Leaves?
When abandonment fear takes over, the mind often jumps straight to the ending.
They're going to leave.
They're going to choose someone else.
I'm going to be alone.
I'm going to be devastated.
I'm not going to be okay.
But sometimes it's useful to slow down and look underneath the prediction.
What are you actually afraid would happen if the relationship ended?
Maybe you fear being alone, or you fear rejection.
Maybe you fear that losing the relationship would prove something painful about yourself – that you are unworthy or unlovable.
Maybe you're afraid you would have to grieve something you desperately wanted to keep.
Or you're afraid you wouldn't know who you are without the relationship.
If any of these were to happen, you’d be faced with feelings and sensations you don’t fully trust yourself to handle or survive—and that, at its core, is the real fear.
How Can You Feel Secure in Polyamory Without Guaranteeing a Relationship Will Last?
One of the difficult truths of loving people is that no relationship comes with a guarantee.
Monogamy, marriage, co-habitation, and having children together doesn't guarantee permanence.
Being someone's "primary" partner doesn't guarantee permanence.
Polyamory simply makes some of these realities more visible.
That can feel terrifying.
But there is also something freeing about it.
You can stop trying to create safety by pretending that loss is impossible.
Instead, you can build safety around something more realistic:
I can love deeply without abandoning myself.
I can be hurt without deciding that I am broken.
I can experience loss without losing my entire sense of self.
I can let relationships change without treating change as proof that I am unworthy.
That is a much sturdier foundation.
How Do You Know If Fear of Abandonment Is an Attachment Wound or a Real Relationship Problem?
There is an important caveat here.
Not every fear of abandonment is an old wound.
Sometimes your partner really is behaving inconsistently, or agreements are being broken.
Maybe you're not getting enough connection and your needs aren't being considered.
Other times, there are genuine incompatibilities.
You may sometimes try to convince yourself that you're "triggered" when you're actually noticing something important.
Abandonment fear isn't always an attachment issue.
Your emotions deserve to be listened to.
The question is whether the fear is telling you:
Something needs to be addressed in this relationship.
Or:
Something painful is happening inside me that needs care.
Sometimes it's both.
Learning to tell the difference is part of emotional maturity.
How Do You Overcome Fear of Abandonment Without Abandoning Yourself?
This became one of the deepest shifts in my own healing.
For a long time, I thought safety meant preventing abandonment.
If I could be loved enough, wanted enough, chosen enough, reassured enough, maybe I would never have to experience that old feeling again.
But eventually I realized that was an impossible job.
I couldn't control whether someone would stay, or how another relationship would develop.
I couldn't control another person's choices.
What I could control was whether I would leave myself when I became afraid.
Would I shame myself?
Would I suppress my needs?
Would I make myself smaller?
Would I panic and try to control the relationship?
Would I abandon my own values because I was afraid someone else might abandon me?
Or could I stay?
Could I say:
I'm scared.
This hurts.
I don't know what happens next.
And I'm still here with myself.
That was a much deeper form of security than anything another person could give me.
What Does Healing Fear of Abandonment in Polyamory Look Like?
Healing doesn't necessarily mean reaching a point where you never fear losing anyone.
It can look much more ordinary—and much less dramatic than we expect.
You notice yourself getting activated when your partner starts a new relationship, and instead of reacting immediately, you pause. You stay with what’s happening inside you long enough to actually feel it.
You name what you’re experiencing, rather than turning it into action right away. You communicate what matters without escalating, withdrawing, or trying to control the outcome.
You ask for support when you need it, and you also learn how to soothe yourself when support isn’t immediately available.
You let grief move through you when something changes, instead of treating it as something to override or fix.
You stop turning your partner’s attention into a scoreboard for your worth. You stop competing for security and start orienting toward clarity.
You become more honest about your needs, and more discerning about which relationships can actually meet them.
And over time, something subtle shifts: the possibility of loss is no longer an emergency signal that takes over your entire system.
Not because you’ve become certain that no one will ever leave.
But because you’ve learned, again and again, that even when something changes—you don’t abandon yourself.
How Does Somatic Therapy Help With Fear of Abandonment?
As a Board-Certified Dance/Movement Therapist and somatic trauma practitioner, I've spent more than 15 years helping people understand and work through the patterns that show up in their relationships.
And one thing I've seen again and again is that insight alone doesn't necessarily change a pattern.
You can understand exactly why you're afraid.
You can know where the pattern came from.
You can recognize that your partner isn't your past.
And still find yourself reacting in the same way.
That doesn't mean you're failing.
It means there is a difference between understanding something and having a new experience of it.
This is one reason I use embodied and relational approaches in my work.
Instead of only talking about what you do when you're afraid someone will leave, we can begin exploring what happens when that fear is actually present.
We don't try to change them. We learn to be comfortable with them.
That's a very different skill from simply knowing that abandonment fear comes from the past.
How Can You Change Your Relationship With Fear of Abandonment?
Fear of abandonment may always be something you recognize from time to time—not just as a thought, but as a felt experience in the body. A tightening in the chest. A drop in the stomach. A rush of urgency. A collapse inward or a surge toward action. This is not just cognitive; it is somatic. It lives in your nervous system, shaped by past experiences of connection, loss, and uncertainty.
A relationship changes.
Someone needs space.
A partner falls in love.
Plans shift.
A relationship ends.
And each of these moments can land not only in your mind, but in your body—activating old patterns of protection, urgency, or shutdown.
But the meaning you make from those experiences can change, especially when you learn to stay present with the embodied experience itself rather than being swept away by it.
Instead of:
They're leaving, so I'm losing everything.
You can begin to notice what is happening inside you in real time—the contraction, the fear, the impulse to act—and gently orient back to the present moment, where something different is also true:
Something is changing, and I can meet this change in my body, breath by breath, without abandoning myself.
Instead of:
If they choose someone else, it means I'm not enough.
You can learn to feel the wave of comparison or inadequacy as it arises in the body—heat in the face, heaviness in the chest, the urge to collapse into shame—and stay connected to yourself long enough to remember:
Their relationship is theirs. My worth is still mine, and I can feel that truth in my body even when fear is present.
Instead of:
I have to make sure they don't leave.
You can begin to notice the urgency that drives control—the racing thoughts, the tightening grip, the impulse to seek certainty—and practice coming back into regulation, into breath, into contact with your own support:
I want to build a relationship where both of us are choosing to stay, and I can feel that choice as something grounded in my body, not something I have to force.
And perhaps the deepest shift is not just cognitive, but deeply embodied:
If someone leaves, I will grieve—and I will feel that grief in my body—but I will not abandon myself in the process. I can stay present with sensation, breath, and emotion without collapsing into self-abandonment.
That is a very different kind of security.
It is not the absence of activation.
It is the capacity to stay in relationship with yourself even when your nervous system is activated by the possibility of loss.
This Is the Work We Explore in Our Polyamory Retreats
This is the kind of embodied relationship work I explore with Dedeker Winston in our polyamory retreats.
We don't expect participants to arrive without fear, jealousy, insecurity, or attachment wounds.
Instead, we create space to experience these patterns differently.
You can slow down enough to notice what happens when fear of loss appears.
You can practice expressing what is actually underneath the fear.
You can experience being witnessed without needing to perform being okay.
You can explore vulnerability, conflict, jealousy, communication, and connection with other people who understand the complexity of non-monogamous relationships.
And most importantly, you can begin developing a relationship with yourself that doesn't depend on guaranteeing that nobody will ever leave.
Because the goal isn't to become someone who never fears abandonment.
It's to become someone who knows:
Even when I don't know who will stay, I know I will stay with myself.
If fear of abandonment is shaping how you experience your polyamorous relationships, join us for a polyamory retreat and experience this work—not just intellectually, but through your body, your relationships, and real-time connection with other people doing the same work.
