Explain the Difference Between a Boundary and an Ultimatum

Boundaries and ultimatums are used interchangeably in most self-help content. They are not the same thing and confusing them leads to either under-enforcement of real limits or the kind of controlling behaviour that is accurately called an ultimatum. This explains the difference with examples and gives you a test to apply before you say anything.
