IFS Self led Boundary Setting
In this dance of life we find ourselves in, finding a healthy balance between caring for ourselves and others is essential to our well-being. I'm mainly thinking here about couples, or people we know well and love, though maybe these ideas can stretch to other relationships too. As always: check inside and see what's right for you.
At the heart of this balance are boundaries.. those essential guidelines that shape how we interact with our loved ones and the world around us.
I'd like to look at boundaries through the Internal Family Systems (IFS) framework, adding in a bit from RLT, holding in mind that both I and many of my clients are neurodivergent and carry a trauma history. I want to explore how to navigate boundaries particularly from the perspective of and with those of us on the receiving end: people whose trauma responses and neurodivergent minds might lead to fawning and shutting down or denial, attack, and blame at times when we get overwhelmed (when our stress buckets are just too full). In IFS terms, we are blended with parts.
I love that in IFS we can see we're a multitude. I have parts on both sides. Parts that can fawn when attacked. And parts that are grandiose and have learnt DARVO ( deny/deflect, attack, and reverse victim-offender) because I internalised it from a traumatised parent. I'll return to DARVO later, because it's worth naming when it shows up in boundary dynamics.
Understanding Boundaries: An ND and Trauma-Affirming Perspective
Boundaries are the guidelines we set for ourselves in relationships, helping us distinguish our own thoughts, emotions, and needs from those of others. They act as an essential tool for protecting our wellbeing while respecting others. They are not walls and it is entirely possible to be loving, kind, and boundaried.
Boundaries can be physical, emotional, intellectual, or time-based. Each one aims to create healthy, respectful connections. When we honour our own boundaries, we create space for meaningful interaction without losing sight of ourselves.
For many neurosparkly/neurodivergent folk and those of us who've grown up in less-than-ideal circumstances (many of us are both), boundaries may not always come naturally or feel intuitive. This is especially true for those with CPTSD and/or rejection sensitivity, where the fear of being misunderstood or judged can shape how boundaries are set or crossed. It's so important to recognise that boundaries are not about shutting others out. They're about honouring our personal needs in a way that's affirming of who we are and how we experience the world.
But what happens when boundaries are challenged or dismissed especially by someone whose unresolved trauma means parts blend quickly? When someone's responses tip into denial, attack, or blame, setting and maintaining a boundary becomes even more critical, and more complicated. Maybe frightening too. Understanding how to protect yourself in these situations while still engaging in a healthy way is key.
Boundaries in IFS
In the Internal Family Systems model, what we're aiming for is our Self (calm, clear, confident compassionate, and courageous) to be the one who, alongside a thoughtful Manager, sets and holds a boundary.
Our Managers are forward-thinking, hardworking inner protectors developed from past experience. One of my favourite things to ask a part when I check inside is: how old are you? More often than not, these Managers are quite young. They're doing the very best job they can. For those of us with heightened sensitivity or different processing frameworks, Managers may be especially vigilant sometimes creating boundary strategies that are a little too rigid or a little too loose. While their goal is always to protect, these strategies can unintentionally create difficulty in relationships.
We may also have reactive boundaries coming from our Firefighters also young (some of mine very fierce teens!), also doing their best, and often spectacularly sweary. Firefighters can be aggressive or frightening to the other person. They may throw up very strong limits more wall than boundary. Or they fawn in reaction to criticism, collapsing the boundary entirely. These are just two of many possible responses.
For those who struggle with rejection sensitivity, or whose experiences have shaped them to anticipate negative reactions, the act of setting a boundary may feel overwhelming .. so when we're in relationship with people whose trauma responses lead them to deny, attack, or blame including DARVO: deny/deflect, attack, and then reverse victim and offender boundaries become vital tools of self-protection. Those responses are not fundamentally about us. They are usually about the other person's unresolved pain. But they make it very hard to maintain a balanced dynamic, and they deserve to be named clearly.
Boundaries Through an RLT Lens: The Orange
Terry Real, founder of Relational Life Therapy, offers one of the most nourishing metaphors I know for understanding boundaries …the orange.
Think of a ripe orange in your hand for a moment.
The outer skin so vivid, textured, slightly tough represents our protective boundary. It's what shields us from the outside world. This is the part that says: I will not let in what is harmful, shaming, or intrusive. It's a filter, discerning what to allow through: warmth, care, and connection can come in; what might bruise or overwhelm is held at the edge. It's strong, but it's not a wall. Porous enough for intimacy, firm enough for safety.
Just beneath the peel lies the white pith soft, fibrous, often overlooked. This inner layer represents our containing boundary: the structure that holds us steady from within. It says: I am responsible for what I send out into the world. I will not lash out, collapse, or spill my pain onto you. It helps us self-regulate. It offers the pause, the breath, the moment of choice before we react.
Both layers are essential. Without the outer, we take in too much. Without the inner, we risk leaking our reactivity onto others.. the Firefighter's territory, and where DARVO lives.
And at the centre of the orange? The vivid, juicy flesh our essence. The centre that is tender, authentic, and entirely worth protecting.
This metaphor reminds us that healthy boundaries are not rigid defences. They are wise, living membranes. They let us stay genuinely connected without losing ourselves, and without overwhelming others.
When both layers are in place, we can say with grounded clarity: I will not take in what harms me. I will not send out what harms you.
In that balance, something beautiful becomes possible. We become safe to ourselves and safe enough to love.
🌿 ND note: if you find one layer harder than the other, you're not alone. Many of us with trauma histories or neurodivergent wiring have had the outer skin worn thin by years of having our limits dismissed leaving us exposed, or swinging into walls for protection. Clarissa Pinkola Estes talks about our need to grow ‘skin’ as it just isn’t there. Many of us haven't had great modelling for the inner pith: the containment that says 'I'll regulate before I react.' Both can be grown, slowly, with practice and Self compassion.
Crafting Healthy Boundaries: A Neuro and Trauma-Affirming Approach with IFS
When something doesn't feel right, pause and tune into what's going on beneath the surface. Which part of you is triggered, and why? Whether it's a recurring issue or a one-time event, identifying the root cause can help you see where a boundary might need to be set.
Turn inside. Different parts will likely have different feelings and thoughts. One part might feel hurt, another might want to mask or avoid conflict, another might just want to run. If it feels right, take a moment to appreciate and validate each of them — even when their views seem contradictory. Like a compassionate mediator, listen to all parts, and then invite them to trust you to find a way to express the boundary with love and honesty. For example:
"When you're late to plans, parts of me feel frustrated and disrespected but I also understand life is unpredictable. I want to find a way to respect both of our needs."
Timing is everything. Choose a calm moment for the conversation ideally when both of you are grounded and have space for honest dialogue. If you're neurodivergent, factor in things like sensory overload or the time needed to process. If you notice yourself starting to blend with parts, that's a signal you may need a mind-body break before continuing.
When you speak, express your needs clearly and vulnerably, without blame:
"I've noticed that when plans shift unexpectedly, I get overstimulated, and I end up feeling disconnected. I really value this relationship and I need some time and structure to feel safe."
If the other person is open to it, invite them to speak for their parts too. If they're unfamiliar with IFS, help them express their feelings without blame. When both sides are heard, finding common ground becomes so much more possible.
Stay grounded, take turns, and if things get heated, ask for a break. This isn't about winning but instead t's about finding something that respects you both. You're a team. You might decide on something practical, like a 15-minute grace period if lateness is a recurring pattern. If the boundary isn't respected, revisit it.
And if you reach an agreement: express gratitude. Thank each other for showing up for this especially if it was hard. Even if you're still working things out, you've built more trust through the process.
A note on Terry Real's feedback approach: I really like his suggestion to give relational feedback little and often, rather than waiting for things to accumulate into a rupture. Small, regular, loving truth-telling keeps the relational field clean. His Feedback Wheel is a wonderful practical tool for this — more on that in the link below.

Remember: not everyone is able to have this kind of conversation. If that's the case, fall back on simpler, clearer boundaries to protect your system. You don't need the other person's cooperation to hold your own pith.
The Art of Balance
Healthy boundaries create space where we can give to others without losing sight of our own needs, and receive from others without feeling overwhelmed. It's not just about saying "no" but about recognising that we have the right to carve out space that respects both our needs and the needs of others. For those with different processing frameworks or trauma histories, this is an ongoing exploration of what feels safe and nurturing.
Boundaries are not walls. They are bridges connecting us to ourselves and to others in healthy, respectful ways. Each of us has unique ways of experiencing the world, and boundaries help ensure we can navigate relationships without feeling overwhelmed or misunderstood. They are quiet declarations of self-worth, and of respect for others. Healthy boundaries aren't just about protection they're about creating a life that feels safe, balanced, and authentically yours, even in relationships where the other person's pain sometimes challenges your peace.
IFS-Informed Boundary Phrases for Heated Moments
Here are a few phrases you might adapt or use as they are when a conversation is getting activated and you notice parts blending, on either side. 🧡
"I'm noticing a part of me getting activated right now it wants to protect, but I want to stay in Self and stay connected with you." (Models unblenching for both of you, and invites calm. Bonus.)
"It sounds like a part of you is really hurting or protecting something tender. I want to hear it and I need us to speak from a calmer place." (Affirms the other's parts without collapsing into them. Best used when you're fairly unblended yourself.)
"There's a part of me that feels blamed and wants to shut down. I care about you and don't want to disconnect so I need a little space to come back to Self." (Creates space without punishment. A pause and a mind-body break is genuinely one of the most effective things you can do here.)
"I'm hearing a part of you that feels deeply misunderstood. I want to hear more and I need us to pause if it's coming out as attack." (Balances compassion with self-respect.)
"I think we might both have protectors up right now. I'd love for us to slow down and take a Mind Body Break twenty minutes or more so we can listen from a more open place." (Shifts from 'you're doing this to me' to 'we're a team, going through a shared human experience.')
"I'm here, and I care. I can stay in this with you but I can't stay right now if we're speaking from blended protector parts." (Maintains relational commitment without abandoning your limits. Say when you'll be back.)
"A part of me wants to argue back but my Self knows that won't help us. Can we come back to this when we're both a little more regulated?" (Taking a mind-body break is maturity, not retreat. Many couples therapy models recommend exactly this, and for good reason. ☺️)
