Good thing you aren't reading too much in to any of this, unlike the 5 caricature opinions you provided.

It's a short story. The ending is lazy in the sense this wasn't a novel or novella. There's nothing out of the ordinary in the ending in context of the format.

The writer is a woman in her late 30s. In all likelihood she hates young attractive women more than you do.

More than likely, this fictional story is based in large part on her own personal experience when she was younger, and updated re the extensive use of texting for communication to be more relevant to modern readers.

Doesn't read anything like it. Women rarely choose as their "avatar" a character that's only positive attribute is nice tits. Margot is likely someone she knew in some form but it's not the writer herself.
