Is AUTHOR wrong in the post ? POST : So i knew this guy and he seems to have a crush on me

While we were talking I find out he is severely depressed and he lives in a constant fear of being abandoned by people he likes
Recently he started using sweet names with me like "cutie" or "potato" which I REALLY don't like,and i find quite bad and embarassing,especially because I don't like him back

I politely asked to stop,and he replied with "why? you're an actual potato"

I kept talking to him asking every time to stop but,at the end,I couldn't handle this anymore,so I ghosted him
He keeps writing,sending messages etc. but i just ignore him 

So,am I the asshole for making his fear of abandonment come true?
