Frequently asked questions

What is the difference between a boundary and an ultimatum?

A boundary states what you will do to look after yourself, for example leaving a conversation that turns into shouting. An ultimatum demands that someone else change or face a punishment. Boundaries describe your own actions; ultimatums try to control another person's.

What is the difference between boundaries and walls?

Boundaries are selective and flexible: they let closeness in while keeping harm out, and they can be explained to the people they affect. Walls block everyone out indiscriminately, usually as a reaction to being hurt, and tend to prevent relationships rather than protect them.

How do you set a boundary with someone?

State the specific behaviour, say plainly what you need, and name what you will do if it continues, then follow through calmly. Short, unapologetic wording works better than long justifications, which invite negotiation.
