How do I know what my boundaries are?

Boundaries are appearing in conversations everywhere. But it can be hard to recognize, articulate, or validate them in our real lives. (It doesn’t help that they’re often confused with rules, or viewed as a concept with no real-world weight). 

Put simply, boundaries are self-defined limits that protect our emotional, physical, and mental wellbeing—and help guide our responses to conditions and behaviors around us. You can explore yours using Reflections—a new self-discovery tool from Feeld. Reflections is designed to help you better understand and communicate what you want from relationships and connections—and where your boundaries lie (what makes you say yes, no, and maybe?).

For now, let’s dive deeper. With the help of sex and relationships therapist Rafaella Fiallo, we’re exploring what healthy boundaries are, what they aren’t, and how to get clarity on yours.

What are personal boundaries?

Personal boundaries are lines we draw in our relationships to uphold the conditions that make us feel happy, safe, and comfortable—and that help to protect ourselves from conditions that don’t. They’re valuable in all kinds of relationships, from “committed” to casual, poly to monogamous, friendly to queerplatonic, even family to workplace. 

There’s no universal set of boundaries that should be set in relationships. Still, here are some types you might consider:

• Emotional boundaries may mark how much emotional labor you can offer others, as well as how much you need back to feel supported.
• Temporal boundaries define how and when your energy is available to others, and how much you need back to feel connected. 
• Physical boundaries lay out what kinds of touch, closeness, or sex you’re OK with, and what’s important to you. 
• Boundaries around non-monogamy clarify what kinds of connections you and your partner(s) are comfortable with—whether you’re open, closed, poly, or something else.

“At its core, a boundary is about saying, ‘this is what I will do to take care of myself or uphold this need that I have,’” says Fiallo. “Boundaries are internally enforced, and guide how we respond to people and situations around us. They’re not about controlling other people’s behavior.”

A simple example of a personal boundary? "Smoke bothers me, so I'll head out once people begin smoking,” Fiallo says. This is different from enforcing a rule on someone else—like, “I don’t like smoke, so you’re not allowed to smoke around me.”

This isn’t to say that standards or expectations around how others should act are necessarily wrong in relationships, Fiallo adds as a caveat. But personal boundaries, specifically, are about your limits and actions. Not about controlling others’.

What are healthy boundaries in relationships?

Productive boundaries in relationships are about you, your limits, and what actions you’ll take to keep yourself safe. But “it’s also worth asking, ‘who does this boundary protect, and at whose expense?’” says Fiallo. “Healthy boundaries support dignity, safety, and agency—not avoidance, punishment, or superiority.” 

If it’s regarding what you feel you can give someone, a healthy boundary will honor your limits while still enabling real, sustainable connection. For example, “I need X amount of me-time to recharge on weekends—but I’d love to connect with you outside of that.”

If it’s focused on what you feel you need from someone, a healthy boundary will name a genuine truth about what you can tolerate, without trying to force a particular outcome. For example, “If my partner is consistently unavailable, that’s my cue to talk to them about it—and if they’re dismissive or avoidant, I might need to reconsider whether this relationship is working for me.” (That’s the difference between setting a boundary and being controlling.)

Healthy boundaries aren't about pushing people away, though, Fiallo emphasizes. “Cutting people off or limiting contact can sometimes be necessary—[but] sometimes it [can be] a form of avoidance dressed up as self-care,” she says. “The work [lies in] discerning which is which, with honesty and compassion.”

Still, if someone dismisses or ignores your boundaries, you might consider whether you want to continue with the connection—and that’s valid, too.

Why is it important to know your boundaries?

“Boundaries protect us against self-abandonment,” says Fiallo. “They help us stay in connection with others without losing ourselves. From a trauma-informed perspective, boundaries are also how we signal safety to our nervous systems—helping us reduce overwhelm and increase trust.”

Practically speaking, knowing our boundaries in a relationship can help to: 

• Prevent us from over-extending ourselves.
• Limit people-pleasing at our own expense.
• Recalibrate conditions that aren’t serving us—or walk away from them, if we need to.

“Without boundaries, relationships tend to default to unspoken contracts, obligations and resentment, and emotional burnout,” says Fiallo.

With this in mind, it’s just as important to be curious about, and respectful of, our partners’ boundaries. Relationship agreements are built to serve everyone.

When you’re unsure of your boundaries 

If you often find yourself “going with the flow” in relationships and connections—responding to the needs and expectations of others without intentionally checking in with your own—it might be a sign you don’t know your boundaries yet. 

The thing is, “‘going with the flow’ often works,” says Fiallo, “until it doesn’t.” Maybe you sense resentment building because parts of the connection or relationship feel at odds with your values or needs. Maybe you feel drained, because your time, energy, or emotional bandwidth is being stretched thinner than you’d like.

These signals don’t mean you’re doing anything wrong. They’re simply information. Often, they can be clues that a boundary exists—but hasn’t been named or communicated yet.

How to identify your boundaries

“Boundaries usually reveal themselves through our emotional and somatic responses,” says Fiallo. Paying attention to how you feel and react in key contexts can offer important clues about where your limits are.

So if you’ve ever been stuck wondering “what are my boundaries, though?” try thinking it through with these steps:

Notice when you feel resentful or shut down

Are there moments when you consistently feel irritated, anxious, or emotionally numb? Maybe it’s when decisions are made without your input, when you’re always the one initiating contact or time together, or when you feel pushed to move faster than you’re comfortable with. 

Identify patterns where you feel drained or pressured

Are there moments where you feel chronically tired or stretched thin? Maybe you’re often the one providing emotional support, or rearranging your schedule to be available. Maybe you notice yourself agreeing to things out of guilt, obligation, or fear of disappointing someone.

Consider when you feel calm and respected

Boundaries don’t only show up through negative emotions. When do you feel most relaxed, heard, and like yourself in a relationship? Maybe it’s when certain needs are met with ease, or you feel free to express yourself without fear of conflict. 

Make space for different needs

“It's also helpful to listen to different ‘parts’ of yourself,” adds Fiallo. “So, the part that wants closeness, the part that wants space, the part that's afraid of conflict. Boundaries often emerge when we honor all those voices rather than letting one run the show.”

Reflect on your values and limits

As well as thinking about the above questions, Fiallo suggests prompts like: 

• What do I need in order to feel emotionally and physically safe?
• What do I feel happening in my body when a potential boundary is challenged?
• What responses do I notice when I feel safe, heard, and like myself?

Feeld’s Reflections tool offers a powerful opportunity to consider your own boundaries—with guided questions designed to help you piece together your needs, limits, and desires in relationships. 

Remember: Boundaries are not static. “They change as we heal, grow, and move through different life stages,” says Fiallo. And staying attuned to them is a skill that takes practice and self-compassion. When it comes to tools like Reflections, identifying your boundaries isn’t a one-time event. You can continue taking the tool as many times as you like, as you and your connections continue to evolve.

How to know when your boundaries are being crossed

Once you’re more familiar with where your boundaries lie, you can develop a stronger understanding of what it feels like when they’re not respected. Common signs that boundaries are being crossed, Fiallo says, include:

• Persistent resentment [towards a person, relationship, or connection].
• Feeling pressured to explain or justify your “no.”
• A sense of walking on eggshells.
• Physical cues like tightness (e.g. in your chest), fatigue, or shutdown.
• Repeatedly betraying your own needs to “keep the peace.”

“When boundaries are crossed, the first step isn't always to leave,” she points out. “It’s often to name what’s happening clearly and calmly, and see how the other person responds. Repair requires accountability—not perfection.”

If you’re wondering how to set boundaries, your Reflections results can be useful here, too. You can share them with others to help them better understand your limits, and where they’re being stretched.

If someone consistently dismisses, mocks, or disregards your boundaries after they've been clearly communicated, that's important data. At that point, the boundary may need to be reinforced—or the connection itself may need to be reevaluated.

But in general, boundaries aren't about pushing people away. “They’re about creating the conditions where real, sustainable connection is possible,” reiterates Fiallo.

Learning your boundaries doesn’t mean drawing hard lines overnight. It’s an ongoing process of paying attention to yourself—your emotions, your body, your energy—and using that information to guide how you show up in relationships. So, be patient and gentle with yourself as you figure yours out and negotiate them with others.

Boundaries tend to become clearer over time, especially as you practice listening to discomfort as data. When approached with curiosity, self-awareness, and honesty, boundaries don’t create distance—they facilitate real closeness, and relationships that support everyone.
