Setting Boundaries: How to Say No Using DBT Skills
We all know that person who seems to effortlessly navigate relationships, somehow maintaining close connections while never appearing overwhelmed or resentful. What’s their secret? More often than not, it’s setting boundaries and maintaining them skillfully. At Gladstone Psychiatry and Wellness, we see firsthand how learning to say “no” and establish limits can transform not just individual well-being, but entire relationship dynamics.
Setting Boundaries: The Foundation of Healthy Relationships
Let’s start with a truth that might surprise you: setting boundaries and limits doesn’t harm your relationships, it helps them flourish. Think of boundaries as the invisible infrastructure that keeps your connections strong and sustainable. When you set appropriate limits, you’re essentially saying, “This is what’s necessary for me to feel safe and comfortable in this relationship.” Far from being selfish, boundaries are actually a recipe for keeping relationships going long-term.
Your boundaries communicate vital information to both you and the other person. They create a framework where trust can grow because everyone knows what to expect. Without boundaries, relationships can become breeding grounds for resentment, confusion, and eventual burnout. When you clearly communicate your limits, you’re giving both yourself and others the roadmap for a healthy, lasting connection.
Discovering Your Personal Boundaries
If you’re struggling to identify what your boundaries are in a particular relationship, you’re not alone. Many people find this challenging, especially if they’ve spent years prioritizing others’ needs over their own. Here are two powerful questions to help you get started:
“What am I willing to accept or do, and what am I unwilling to accept or do?” This question helps you clarify your comfort zones and deal-breakers. Be honest with yourself. There’s no judgment here, only self-awareness.
“Has this person ever done something that felt like it crossed a line?” Sometimes we don’t know where our boundaries are until someone steps over them. That uncomfortable feeling you get when someone pushes too far? That’s valuable information about what you need to protect.
Remember, it’s perfectly normal to update your boundaries over time. As you grow and change, and as your relationships evolve, your limits might shift too. This isn’t inconsistency, it’s healthy adaptation.
The Truth About Boundary Violations
Here’s something that’s important to understand: only you can violate your own boundaries. Other people can’t actually cross your boundaries. They can only behave in ways that prompt you to respond according to your predetermined limits.
This might sound confusing at first, but it’s actually empowering. Your boundaries don’t say, “You can’t do this thing to me.” Instead, they say, “If you do this thing to me, this is how I will react.”
Let’s look at a practical example. Suppose you have a friend who repeatedly calls you late at night, waking you up, and you’ve decided you don’t want to be disturbed after a certain hour. You have already tried asking the friend not to call you late at night to no avail. An effective boundary might sound like this: “I will not answer my phone after midnight. When I go to bed, I’ll silence my phone, and if calls come in, I won’t answer them.”
Notice the difference? You can’t control whether your friend calls, that’s their choice. But you can absolutely control how you respond to those calls. This shift in perspective moves you from victim to empowered decision-maker.
DBT Skills: Your Boundary-Setting Toolkit
In Dialectical Behavior Therapy (DBT), we teach interpersonal effectiveness skills that are incredibly helpful for setting boundaries and maintaining them. Two skills that work particularly well for setting boundaries are DEAR MAN and FAST.
DEAR MAN helps you communicate your boundaries clearly and effectively:
- Describe the situation objectively.
- Express your feelings and thoughts about it.
- Assert what you need or want.
- Reinforce why this matters to you and the relationship.
- Mindful – stay focused on your goal.
- Appear confident in your delivery.
- Negotiate only when appropriate and necessary.
FAST helps you maintain your self-respect while setting boundaries:
- Fair – be reasonable to both yourself and others.
- (no) Apologies – don’t apologize for having needs.
- Stick to values – stay true to what matters to you.
- Truthful – be honest about your limits. Don’t lie or make up excuses.
These skills take practice, and they’re incredibly effective for creating the kind of relationships where everyone feels respected and valued.

Setting boundaries isn’t about building walls—it’s about creating healthy spaces where relationships can thrive. Remember, you deserve to feel safe, comfortable, and respected in all your relationships. Learning to say “no” when necessary isn’t selfish.
