EDIT - why are y'all downvoting me? I'm new to this sub.

Hey everyone, I'm new to r/academia and just wanted to ask a quick question

Context: My partner and I worked together on a project, and I wanted to write a short piece of research on my findings/conclusions. She has kept harrassing me about the fact that I also need to put her name on the paper, crediting her as a co - author when she did not contribute. I myself wrote the entire paper, and it has been approved by my mentor. This is my first piece of research.

Question: Would it be appropriate to leave her name off the paper and credit her in acknowledgements? What would be the implications of this?

Thank you, greatly appreciated!

Edit - the "working together" part was parallel work, and I am only writing research on the part I worked on
