AITA for getting mad over my ex liking celebrity's too much

So i (M highschooler) was in a relationship with my ex(F highschooer ) for some months and i knew she had crushes on celebrities from the start, she was obsessed with them and she always used to send me billie eilish edits ( which wasn't even a problem for me ) or bellingham edits which pissed me off. She didn't only like bellingham. She liked many other celebrities and crushed over them like zayn malik or Justin Bieber. I don’t have problems with someone liking those celebrities, but why was she sending them to me ?? I told her many times that i don’t like her sending me edits of those celebrities and telling me their fine ,she would apologise and stop sending them for a while and then start sending one or 2 edits after some time being passed. I've never actually crushed over a celebrity and i think its childish and dumb but i still tried to learn about Billie eilish or harry styles or other celebrities she liked so i could understand her better, but one time when i was telling her that i like cars and i want to have multiple cars in the future she told me its stupid and made fun of me and told me im childish... and she did a small apology after and told me it's because of nicotine ( she's a nicotine addict and because of ramadanshe'ss fasting and can't smoke, so she gets mad easily ). And i got done with her and left her ( this is not the only reason for me leaving). So, AITA ????
