If you love someone who struggles with addiction, you have probably heard the word “boundaries” more times than you can count.
Set boundaries. Hold boundaries. Have better boundaries.
But what does that actually mean when the person you love is hurting, asking, blaming, withdrawing, promising, relapsing, or telling you that you are the only one who can help?
Boundaries are not ultimatums, and understanding that difference can help you set limits with more clarity and confidence.
In real life, boundaries are not neat little sentences you write in a journal during a calm afternoon. They happen with your heart pounding, your stomach knotted, and every part of you wanting to make the discomfort stop. Which is exactly why they feel so confusing.
You may know, deep down, that something needs to change. But when it comes time to actually say no, you feel guilty, cruel, selfish, or frightened. This is especially true when addiction is involved. Over time, your nervous system learns to treat another person’s distress as your emergency. So when you try to set a boundary, it can feel less like self-protection and more like abandonment.
If saying no brings up a wave of guilt, you may also find it helpful to read Why Saying No Feels So Guilty — Even When It’s Healthy.
Here’s what I want you to hold onto as you read this: a boundary is not about punishing someone, controlling them, or proving a point. A healthy boundary is about staying connected to yourself when someone else’s behaviour is harming your wellbeing, peace, or integrity. It is a way of saying, “I love you, and I also matter.”
What a Boundary Actually Is
Boundaries are not a way to force someone to stop drinking or using drugs. They are decisions about what you will do to protect your wellbeing, finances, home and children. For a broader look at what you can and cannot influence, read What Can I Do to Make My Loved One Stop Drinking or Using Drugs?.
A boundary is a clear limit around what you will do, what you will participate in, and what action you will take to protect your own wellbeing.
Healthy boundaries are important in all relationships, and HelpGuide offers a helpful general overview of setting healthy boundaries in relationships if you want to understand the wider foundations before looking at how addiction can complicate them.
Stating a boundary is not the same as setting a rule for another person to follow.
This is where many people get tangled.
A boundary is not, “You are not allowed to drink.” A boundary might be, “I will not stay in the house when you are drunk and aggressive.”
A boundary is not, “You have to stop using drugs.” A boundary might be, “I will not give you money, because I am no longer willing to fund something that may harm you.”
A boundary is not, “You must go to rehab.” A boundary might be, “I am willing to support recovery steps, but I am not willing to keep pretending everything is fine when nothing is changing.”
Notice the difference? A boundary is not about taking control of their choices. It is about taking responsibility for your own. Instead of asking, “How do I make them stop?” a boundary asks, “What do I need to do to stay safe, sane, and true to my values?”
That may sound simple. It is not always easy. Simple and easy are distant cousins.

Boundaries Are Not Ultimatums
This is a question worth slowing down for, because a boundary and an ultimatum can sound similar on the surface.
An ultimatum is usually an attempt to control another person’s behaviour through threat or emotional pressure. It says, “Do what I want, or else.” Often it is issued in a heated moment with no real intention of follow-through.
A boundary says, “You get to make your choices, and I will make mine.”
The difference is not always in the wording. It is in the intention and the follow-through. “If you drink again, I’m leaving” could be an ultimatum if it is said to frighten someone into stopping, with no real plan behind it. It could also be a genuine boundary if it comes from a calm, clear recognition that you can no longer live this way — and you mean it.
The question to ask yourself is honest and simple: am I trying to control their behaviour, or am I telling the truth about my own limits?
A healthy boundary also does not require the other person to agree with it, like it, or approve of it. If your boundary is only valid when they accept it, it is still waiting for permission to exist. That is not a boundary yet. That is a request.
How to Form a Boundary
Before a boundary can be communicated, it needs to be formed privately — and this is the step most people skip.
They wait until everything explodes, then try to set a boundary in the middle of a crisis. Sometimes that is unavoidable. But where possible, it helps to think clearly before the next storm arrives.
Start by asking yourself what is no longer sustainable. What keeps happening that is costing you your peace, your health, your sleep, your finances, or your sense of self? What have you been tolerating because you are afraid of what might happen if you stop?
Then ask: what is within my control here?
This question matters deeply because addiction can pull you into trying to manage things that are not yours to manage. You may not be able to control whether they drink, use, lie, rage, deny, or seek help. But you may be able to control whether you give money, stay in the conversation, cover the consequences, allow access to your home, or continue pretending that something is okay when it is not.
Once you know what is within your control, form the boundary around that.
A useful sentence structure is: “When this happens, I will do this.”
For example: “When you ask me for money, I will say no.” Or: “When you yell or insult me, I will end the conversation.” Or: “When you are intoxicated, I will not discuss anything serious.”
Be specific enough that you can actually follow through. A vague boundary is hard to hold. “I need you to respect me” is true, but it is not specific enough to guide your actions. What does respect look like in this situation? Name it clearly — no shouting, no asking for money, no coming home intoxicated and expecting everything to be fine.
One more thing: start with a boundary you can actually hold. A smaller, realistic boundary you follow through on is far more powerful than a dramatic one you collapse on by morning.
If you find yourself feeling responsible for whether they recover, When You Feel Responsible for Their Recovery may help you gently sort what is yours to carry and what is not.
Before a boundary is spoken out loud, it often begins in a quieter place — with honest reflection about what is no longer sustainable.
How to Communicate a Boundary
A boundary is best communicated when things are as calm as possible. Not always calm — sometimes calm is a luxury item, like a matching Tupperware lid — but calmer is better where you can manage it.
Try not to communicate a boundary in the middle of panic, rage, or emotional exhaustion. You are more likely to over-explain, soften, or backtrack.
Keep it simple. You do not need to present a legal case. You do not need to list every painful thing that led you here. The more words you use, the more openings there are for debate, denial, or bargaining.
A clear boundary might sound like:
“I care about you, and I need to be honest about something. I am no longer willing to give you money. If you ask, the answer will be no. I can help you find support, but I will not give cash.”
Or: “I’m willing to talk when we’re both calm. I won’t have serious conversations when you’ve been drinking. If that happens, I’ll pause and come back to it another time.”
Or: “I love you. I am not willing to be shouted at or insulted. If that starts, I will end the conversation.”
Notice these are not long speeches. Clear is kind. Clear is also harder to twist.
And expect pushback. If the relationship has been operating without clear limits for a long time, the first boundary may not be received with open arms. The other person may react with anger, blame, pleading, promises, or escalation. That does not automatically mean your boundary is wrong. It often means the old pattern has been interrupted.
This is also why support matters. Holding a boundary while someone you love is distressed or furious is genuinely hard. A trusted friend, counsellor, coach, or support group can help you stay grounded in what is real.
If there is any threat of violence, coercive control, or unsafe behaviour in your situation, please plan boundaries carefully with appropriate professional support. Safety comes first. A boundary that increases danger needs a different strategy, not just a braver sentence.
Communicating a boundary does not need to be harsh or dramatic. Often, the strongest boundaries are spoken simply, calmly, and clearly.
Holding the Boundary
Holding a boundary means doing what you said you would do. Not perfectly. Not without guilt. Not without your hands shaking. It means that when the limit is crossed, you return to the action you chose.
If the boundary is, “I will end the conversation if you call me names,” holding it sounds like: “I’m going to end this conversation now. We can talk later when we’re both calm.” Then you hang up, leave the room, or stop replying.
The hard part is usually not the sentence. It is surviving the emotional weather that follows — the bargaining that starts up in your own mind. Maybe I was too harsh. Maybe I should explain one more time. Maybe they really need me this time.
This is where it helps to remember: holding a boundary is not the same as withholding love. You can feel compassion and still refuse to participate in harm. You can understand someone’s pain and still stop making yourself available for it. You can love someone deeply and still allow them to experience the consequences of their own choices. That does not mean you stop caring. It means you stop making yourself the barrier between them and reality.
Sometimes the peace comes slowly — not because everything outside you has changed, but because you have stopped abandoning yourself inside it.
When You Break Your Own Boundary
You probably will, at some point. Let’s take the shame out of that right now.
You might answer the phone after saying you would not. You might give money again. You might soften the boundary because they cried, raged, or sounded genuinely desperate.
This does not mean you failed. It means you are human, learning a new way of responding under pressure that your nervous system has not caught up with yet.
This is also why I believe it can be more compassionate and accurate to understand many so-called codependent behaviours as coping strategies, which I explore more in What Is Codependency — and Why Did Coping Strategies Get Labelled as a Character Flaw?.
The better question is not, “How do I never mess this up?” It is, “How do I come back to myself when I do?”
You can repair with yourself. You can reflect on what happened, what you felt, what support you needed, and what you would do differently. You can recommunicate the boundary if needed. You can make it smaller, clearer, or more realistic.
Boundary work is not a performance. It is a practice. And like any practice, you get stronger by returning to it — not by being flawless.
The Grief Nobody Mentions
One thing that does not get talked about enough is that healthy boundaries can bring grief.
You may grieve the relationship you wished you had. You may grieve the version of the person you miss, or the hope that if you just loved them well enough, things would finally change. You may even grieve the role you played — the helper, the fixer, the one who held everything together — even if that role was exhausting you.
If you are carrying grief that does not have an easy name, Grief You Haven’t Named: The Hidden Cost of Loving Someone With Addiction may help you feel less alone in what you have been holding.
This does not mean you should go back. It means you are being honest about the cost of change.
Boundaries often ask us to stop living inside a fantasy and face what is actually happening. That can be painful. But it can also be the beginning of something else — because once you stop pouring all your energy into controlling the uncontrollable, some of it slowly starts returning to you. Your sleep. Your health. Your friendships. Your sense of self. The life you still get to have.
You Are Allowed to Matter Here
A boundary is not a withdrawal of love. It is a refusal to abandon yourself.
You are allowed to have limits. You are allowed to protect your peace. You are allowed to stop participating in patterns that are hurting you. And you are allowed to say, “I can love you, and I can no longer do this.”
That sentence may feel heavy at first. But it may also become a doorway — not necessarily to the outcome you wanted with them, but to a steadier, more honest relationship with yourself.
You matter. Not only as the helper, the strong one, the forgiving one, the one who understands. You matter as a whole person, with needs, limits, and a life worth protecting.
When you remember that boundaries are not ultimatums, it becomes easier to set limits from self-respect rather than fear or control.
Boundaries do not make you unloving. They help you love without disappearing.
A Gentle Next Step
If you are beginning to realise you have been carrying too much, start small. Choose one repeated pattern that is costing you. Name what is within your control. Form one boundary around your own behaviour, not theirs.
Then think about what support you need to hold it.
You do not have to do this perfectly. You do not have to do it all today. You only need to begin returning to yourself, one honest limit at a time.
That is a very brave beginning.
