Friend vs boyfriend situation

I have a boyfriend that is honestly so sweet, cute and just overall amazing. Everyone in my life likes him except for one friend.

The other day she told me she dislikes him and called him rude because he’s quiet and supposedly gave her a dirty look (I know he wouldn’t do that) she told me to change him and make him more outgoing but I don’t want to change him for her approval. I also know she doesn’t like a lot of people and a lot of people don’t like her ( yes I’m in high school). Meanwhile her bf called me stupid and other hurtful things.

I’m not sure what to do in this situation because both parties mean a lot to me but lately I’ve been questioning my friendship with this girl due to her attitude and rude comments.
