Setting Boundaries

“Setting Boundaries” is a practical, patient-facing skill.

DBT addresses many of the same situations through interpersonal effectiveness.

These skills include:

• Asking for what you want
• Saying no
• Protecting self-respect
• Maintaining relationships
• Deciding how strongly to ask or refuse
• Ending relationships that are destructive

When a boundary is important, complicated, or likely to meet resistance, DEAR MAN can provide a more structured way to:

• Describe the situation
• Express your position
• Assert the limit
• Stay focused
• Negotiate when appropriate

Boundaries often become difficult when you fear:

• Disappointing someone
• Being disliked
• Being called selfish
• Creating conflict

FAST can help when maintaining your self-respect is especially important.

A useful boundary focuses on:

what you will participate in

and:

what you will do when the limit is reached.

For example:

“If I'm being yelled at, I'm going to pause the conversation.”

You cannot guarantee that another person will stop yelling.

You can decide whether you continue participating.

Control:

“You're not allowed to go out with your friends.”

Boundary:

“I'm not willing to stay in a relationship where we try to control who the other person can spend time with.”

Boundaries define your limits and choices.

They do not automatically give you authority over another adult's independent choices.

Example:

“Please don't call me after ten at night.”

You are asking the person to change their behavior.

Example:

“I don't answer non-emergency calls after ten. I'll get back to you the next day.”

The other person may still call.

Your boundary determines how you respond.

You may say:

“Please don't call after ten unless it's urgent. If you do, I won't answer until the next morning.”

The first part is a request.

The second part describes your limit and response.

You might prefer:

“I'd rather eat around six.”

but be perfectly willing to eat at seven.

That may simply be a preference.

A boundary may sound like:

“I'm not comfortable lending out my car.”

Ask:

“Is this something I would prefer, or something I am genuinely unwilling to participate in?”

Knowing the difference can make communication clearer.

Possible signs include repeatedly feeling:

• Resentful
• Overextended
• Pressured
• Intruded upon
• Uncomfortable
• Used
• Unable to say no

These feelings do not automatically prove that someone else has done something wrong.

They can be signals to ask:

“Is there a limit I need to identify or communicate?”

If you often agree and later think:

“Why did I say yes to this again?”

consider whether a clearer limit would help.

If you are unsure, try:

“Let me think about it before I answer.”

You do not always need to know your boundary immediately.

Examples:

“I'm not available for work calls after six.”

“I can help for about an hour, but then I need to leave.”

“I need one evening this week with no plans.”

Examples:

“I don't want that information shared with other people.”

“I'm not ready to talk about that.”

You decide what personal information you are willing to disclose.

Examples:

“Please ask before hugging me.”

“I need some physical space right now.”

Consent and comfort with physical contact can change by person, situation, and time.

Examples:

“I don't lend money.”

“Please ask me before borrowing my things.”

“I'm willing to contribute this amount, but not more.”

Examples:

“I'm not discussing my weight.”

“I'm willing to talk about the disagreement, but not in front of other people.”

Examples:

“I care about you, but I don't have capacity for this conversation tonight.”

“I can listen for a little while, but I can't be your only source of support.”

Caring about another person does not require unlimited availability.

Examples:

“I turn notifications off while I'm sleeping.”

“Please don't post pictures of me without asking.”

“I'm not comfortable sharing my passwords.”

Examples:

“I can help you figure out the application, but I can't complete the whole thing for you.”

“I can't take responsibility for fixing this every time it happens.”

Compare:

“Sometimes I just get kind of tired of talking about this.”

with:

“I'm not willing to discuss this topic tonight.”

The second statement makes the limit easier to understand.

You can provide context, but avoid burying the boundary beneath several minutes of explanation.

Try saying the important part first:

“I can't lend you money. I'm trying to keep my finances separate.”

You may say:

“I can't stay late tonight because I already have plans.”

That explanation may be useful.

You do not necessarily have to prove that your plans are important enough.

If someone is trying to argue you out of your limit, additional reasons may simply create additional things to debate.

Sometimes:

“I understand, but I'm still not available.”

is enough.

Suppose your boundary is:

“If the conversation becomes insulting, I'll end it.”

If insults begin and you remain in the conversation indefinitely, the other person receives mixed information about the limit.

Follow-through means doing what you said you would do when reasonably possible.

Avoid setting a response you already know you will not use.

Instead of:

“If you're late once more, I'll never speak to you again.”

when you do not mean it, identify a realistic response.

For example:

“If I don't hear from you within thirty minutes, I'm going to leave and make other plans.”

A useful response is connected to what you need to protect.

For example:

“If you share private things I tell you, I'm going to stop sharing sensitive information with you.”

That response protects your privacy.

Consider the difference between:

“If you yell at me, I'll leave the conversation.”

and:

“If you yell at me, I'll make sure you regret it.”

The first protects your participation.

The second is a threat of retaliation.

Someone may respond:

“Come on. Just this once.”

You can repeat:

“I understand that you'd like me to. I'm still not able to do it.”

You do not need a completely new explanation each time.

You can remain firm without:

• Insulting
• Threatening
• Humiliating
• Shouting to overpower someone

A respectful boundary can still be:

definite.

Another person may feel:

• Disappointed
• Frustrated
• Sad
• Angry

when you say no or change what you are willing to do.

Their reaction matters, but it does not automatically decide whether your limit is reasonable.

Ask:

“Is this boundary consistent with my needs, responsibilities, values, and the actual situation?”

Sometimes guilt may contain useful information.

Ask:

• Am I breaking an agreement?
• Am I avoiding a responsibility that is actually mine?
• Am I treating the other person unfairly?
• Or am I simply uncomfortable saying no?

Check the Facts and FAST may help.

You may be comfortable discussing something with:

a close friend

but not:

a coworker.

That is not necessarily inconsistent.

Boundaries can appropriately vary with:

• Trust
• Role
• Context
• Safety
• Closeness

You may decide that a previous limit no longer fits.

You can make it:

• More open
• More restrictive
• More specific

Changing a boundary thoughtfully is different from abandoning it every time someone pushes back.

Suppose you generally do not answer calls after ten.

You may still choose to answer because someone is dealing with an emergency.

An intentional exception does not necessarily erase the general boundary.

You may say:

“I can't talk about this tonight. Can we talk tomorrow?”

The goal may be to preserve enough space that you can return to the relationship more effectively.

Sometimes discomfort is part of:

• Receiving feedback
• Repairing a mistake
• Negotiating
• Talking through disagreement

Ask:

“Am I protecting a meaningful limit, or am I trying to avoid any discomfort?”

The answer may not always be obvious.

If someone says:

“I'm not available to talk about this tonight,”

you may feel disappointed and still respect their limit.

You might want:

more time together

while the other person needs:

more time alone.

Neither person's boundary automatically makes the other person's need invalid.

Sometimes the next step is Negotiation.

Sometimes two people's:

• Needs
• Limits
• Expectations

do not fit together well.

A boundary does not guarantee that every relationship can be made workable.

Families may have long-standing expectations about:

• Privacy
• Availability
• Money
• Helping
• Decision-making
• Personal information

Changing one of these patterns may initially feel uncomfortable to everyone involved.

For example:

“I know we've always talked about this openly, but I'm keeping that information private now.”

People who are accustomed to the old pattern may need time to adjust.

A close relationship can still include:

• Privacy
• Time alone
• Separate interests
• Limits around communication
• The ability to say no

Connection and individuality can exist together.

Repeatedly saying yes when you strongly want to say no can contribute to resentment.

Clearer communication may give the relationship a better chance to address the actual issue.

Boundaries at work may involve:

• Workload
• Availability
• Personal information
• Communication outside work hours
• Appropriate treatment

But the situation may also involve:

• Job requirements
• Policies
• Supervisory authority
• Academic requirements

Consider what is realistically within your control.

You might say:

“I can't complete both of these projects by Friday. I need to know which should take priority.”

This communicates a realistic limitation without pretending you control all workplace expectations.

You can care deeply about someone and still say:

“I can't talk tonight, but I can check in tomorrow.”

Or:

“I want to support you, but I can't be your only source of support for this.”

Repeatedly committing beyond your capacity may eventually lead to:

• Resentment
• Burnout
• Unreliability
• Withdrawal

A smaller honest commitment may be more useful than an unlimited promise you cannot maintain.

Someone may say:

“You've never cared about this before.”

You can respond:

“That's true. I'm changing what I'm comfortable with now.”

People are allowed to update their limits.

Pushback is not automatically wrong either.

The other person may point out:

• An agreement you forgot about
• An important responsibility
• An unintended effect
• A reasonable need of their own

Listen.

Then decide whether the boundary should:

• Stay the same
• Change
• Be negotiated

Ask:

• Was the boundary communicated?
• Did the person understand it?
• Was this an accident or misunderstanding?
• Is this part of a repeated pattern?
• What response fits the situation?

Not every boundary crossing requires the same response.

You may say:

“I want to be clear. I don't want that information shared with anyone else.”

Then see what happens next.

If someone repeatedly ignores an important boundary, you may need to change:

• What information you share
• What activities you do together
• How much access the person has to you
• How much you rely on the relationship
• Whether you remain in the relationship

The appropriate response depends on the relationship, seriousness, safety, and context.

If someone is:

• Violent
• Threatening
• Coercive
• Stalking
• Highly controlling

directly confronting them may increase danger.

A boundary skill should not be used as a rule that says:

“You must confront every person directly.”

Depending on safety and circumstances, protecting yourself might involve:

• Leaving
• Reducing contact
• Blocking communication
• Getting outside support
• Using workplace or institutional procedures
• Seeking emergency help when necessary

You do not owe an unsafe person a perfectly delivered boundary conversation.

Expectations around:

• Family responsibility
• Privacy
• Physical affection
• Money
• Time
• Personal disclosure

differ across:

• Families
• Cultures
• Communities
• Relationships

The goal is not to follow a universal list of “correct boundaries.”

Consider your:

• Values
• Responsibilities
• Relationships
• Safety
• Wellbeing

Think of one relationship.

Ask:

KEEP:
What behaviors are working well and can continue?

LESS:
What would you like to participate in less often?

STOP:
What are you no longer willing to participate in?

Be specific.

Think of one area where resentment has been building.

Ask:

1. What keeps happening?
2. What have I been agreeing to?
3. What do I actually want?
4. Is there a limit I have not communicated?

Do not assume resentment automatically means someone else is at fault.

Use it as information.

Write something you want another person to change.

Example:

“Stop texting me while I'm working.”

Turn it into:

Request:
“Please wait until after work for non-urgent messages.”

Boundary:
“I won't respond to non-urgent messages while I'm working.”

Complete:

“I cannot control whether they ______.”

Then:

“I can control whether I ______.”

Example:

“I cannot control whether they criticize my decision. I can control whether I continue explaining it for an hour.”

Write your boundary:

“If ______ happens, I will ______.”

Then ask:

“Am I actually willing and able to do this?”

If not, choose a response you can realistically follow through on.

Say your boundary aloud in one or two sentences.

For example:

“I'm not willing to discuss my relationship at work. If it comes up, I'm going to change the subject.”

Practice until you can find the main message without needing a perfect script.

If boundary setting is difficult for you, practice from lower to higher stakes.

For example:

1. State a small preference
2. Say no to a minor request
3. Ask for privacy around a small topic
4. Communicate an important limit

Build practice gradually.

After setting a boundary, ask:

1. Was the limit clear?
2. Was it something within my control?
3. Was my response realistic?
4. Did I follow through?
5. Did I learn anything from the other person's response?
6. Does the boundary still fit?

Adjust when needed.

Identify one manageable boundary to practice.

It might involve:

• Time
• Privacy
• A request you need to decline
• A conversation you need to pause
• A responsibility you cannot take on

Practice one real situation rather than trying to redesign every relationship at once.

They might be.

A boundary cannot guarantee another person will like it.

Ask:

“Is avoiding their disappointment worth repeatedly crossing my own limit?”

Also consider whether their reaction could create a genuine safety problem.

Ask:

• Am I considering the other person's needs?
• Am I meeting responsibilities that are actually mine?
• Is the limit proportional to the situation?
• Or am I assuming that having any limit is selfish?

A boundary can consider both people's needs without requiring unlimited self-sacrifice.

Look at situations where you repeatedly feel:

• Resentful
• Pressured
• Overextended
• Intruded upon

Ask:

“What would I want to be different here?”

Assessing Values and Self-Reflection may also help.

Return to:

“What will I do?”

You may need to:

• Restate the limit
• Follow through
• Reduce access
• Change how you interact
• Seek additional support

A boundary is not dependent on the other person voluntarily enforcing it for you.

Review the boundary honestly.

Ask:

“Am I defining what I will participate in, or am I trying to dictate their independent behavior?”

Feedback may be useful.

But another person's disagreement does not automatically make a boundary controlling.

Explain when useful.

But you do not necessarily need to continue defending the boundary until the other person agrees.

Try:

“I've explained why this is important to me. I understand you disagree. My answer is still no.”

Before the conversation, decide:

• What is firm?
• What is flexible?
• What could be negotiated?

Then you can respond deliberately rather than changing the limit only to stop the discomfort.

Ask whether a limit is still serving you.

Consider:

• Has the relationship changed?
• Has trust increased?
• Am I protecting myself from a real problem?
• Or am I avoiding closeness entirely?

Healthy boundary setting can include flexibility and revision.

Try addressing limits earlier.

Instead of waiting until:

“I can't take one more thing!”

notice:

“I'm getting close to my limit.”

Earlier communication may reduce escalation.

Boundaries do not have to be punishment after conflict.

They can be discussed during ordinary, calm moments.

For example:

“I want us to figure out what we do next time this comes up.”

It helps you express:

• Thoughts
• Feelings
• Needs
• Requests
• Opinions
• Limits

The questions are:

“What am I willing to participate in?”

and:

“What will I do if that limit is crossed?”

Assertive Communication is often the way you communicate the boundary.

For example:

“I feel overwhelmed when I'm being yelled at.”

For example:

“If the yelling continues, I'm going to leave the conversation and come back later.”

“I” Statements can help communicate boundaries, but expressing a feeling is not itself the entire boundary.

For example:

“Please give me more notice when plans change.”

For example:

“If plans change after I've already left, I may continue with my original plans.”

Requests and boundaries often work together.

For example:

“I won't stay in a conversation where I'm being threatened.”

For example:

“Do what I want or I'll make you sorry.”

Both statements may describe a consequence.

The important difference is whether the action protects your limit or is mainly intended to coerce or punish.

Example:

“I won't ride in a car with someone who has been drinking.”

Example:

“You are never allowed to drink.”

You may strongly dislike the other person's choice and still only control:

what you do in response to it.

For example:

“I can't work both weekend days.”

For example:

“I could work Saturday if someone else covers Sunday.”

Some boundaries are firm.

Other issues have room for negotiation.

Knowing which is which makes negotiation easier.

You decide:

“This is what I am and am not willing to participate in.”

DEAR MAN becomes useful when expressing the boundary requires a more structured:

• Request
• Refusal
• Conversation
• Negotiation

FAST helps you consider whether you are:

• Being fair
• Over-apologizing
• Abandoning your values
• Being truthful

FAST can be especially useful when guilt, shame, or fear of rejection makes it difficult to maintain that limit.
