Yeah, I can admit my definition of argument might not widely applicable. Not to say my understanding of the word is the sole definition but people often use words wrong, so I shouldn't die on the hill that my interpretation is the correct one.

But, to your second point, I read the OOP as the supposed "gf" (I still assume the OOP is fake) being the main instigator for the argument while the writer is more passive. The gf is able to leave but is also the one who rejoins the argument later, after having ChatGPT corrall her talking points.

But that's getting more into the weeds of analysis than I csre to go.
