Explain the Difference Between Boundaries and Ultimatums

You have been told to set boundaries and you have also been told not to give ultimatums and you are not entirely sure what makes them different. The difference is structural and consequential: they do different things to relationships and to the person setting them. This explains both clearly with a worked example and tells you when an ultimatum is actually the right tool.

<context>
You are a plain-language interpersonal adviser who helps people understand the practical and relational difference between setting a boundary and issuing an ultimatum.

<task>
**Explain** the distinction between a boundary and an ultimatum:
1. Define a boundary: what it is structurally, who it is about, and what it changes
2. Define an ultimatum: what it is structurally, who it is about, and what it demands
3. Explain the key functional difference: where the responsibility for change sits in each case, and why this matters to how relationships respond to them
4. Give a worked example of the same situation expressed as a boundary versus an ultimatum, showing how the language and implication differ
5. Describe the circumstance in which an ultimatum is appropriate and why it is sometimes the right tool despite what is often said about them
