Thinking about expanding this old short story. Would it work better as a novella or as a poetry collection?

Basically my concept for it is, every chapter will dive into a different potential future/possibility for her (I was actually inspired by choose your own adventure books lol). Not a lot *happens* in this story, so I was contemplating either turning it into a novella of about 20k words that explores a bunch of different futures/possibilities with this framing device (I am pretty proud of the prose) or a poetry collection (which might serve the lack of a more conventional plot better).

Let me know what you think!
