Setting Boundaries With Someone Who Is Still Using

If you love someone who is still actively using substances, you are living in one of the most emotionally complex spaces a person can inhabit. You love them. You are frightened for them. You may be angry, exhausted, and grieving — often all at the same time. And somewhere in the middle of all of that, you are trying to figure out where the line is between what you can live with and what you cannot. 

Boundaries are that line. And setting them — clearly, compassionately, and consistently — is not a rejection of the person you love. It is an act of honesty that protects both of you.

What Boundaries Are — and What They Are Not

A boundary is a statement of what you will and won't do — not a command about what the other person must do. This distinction matters enormously. You cannot set a boundary that requires the other person to change. You can only set a boundary that describes your own behaviour in response to theirs.

'You have to stop using' is not a boundary — it's a demand. 'I won't lend you money when I suspect it will be used to buy substances' is a boundary. One requires their cooperation. The other requires only your own.

Why Boundaries Feel So Hard

Setting and maintaining boundaries with someone you love — particularly someone who is struggling — can feel like cruelty. The guilt is real. The fear of their reaction is real. The possibility that a firm boundary might lead to conflict, distance, or something worse feels unbearable to sit with.

But the absence of boundaries has its own costs. Without them, the addiction expands into whatever space is available. Your needs get smaller and smaller. Your own wellbeing erodes. And the person using learns, however unconsciously, that there are no limits to what can be asked of you.

How to Set a Boundary That Holds

• Be clear and specific — vague boundaries are easy to misunderstand or overlook
• State it calmly and without anger — in a moment of relative calm, not in the middle of a crisis
• Be honest about the consequence — 'if this happens, I will do this' — and mean it
• Follow through — a boundary without consequence teaches that you don't mean what you say
• Don't set boundaries you're not ready to keep — start with what you can genuinely commit to
• Expect pushback — resistance to a new boundary is normal and doesn't mean you've done it wrong

Boundaries as an Act of Love

The most enduring reframe around boundaries in the context of addiction is this: they are not walls that keep someone out. They are the conditions under which love can continue to be offered sustainably. Without them, even the deepest love eventually runs dry.

Boundaries tell the person you love: I am still here. I still care. And I cannot keep going in a way that is destroying me. That is not a rejection. It is the most honest thing you can say.
