is she jealous or just arrogant?

[Jane]

You should stop being friends with her. There's no point being around someone like that. She sounds like a really pathetic attention seeker. She copies anime characters to try seem cute? That's unbelievably sad and cringey. She's obviously jealous too, which is why she always feels she needs to insult things like your bracelet. Even if she wasn't jealous and that's what she really thought, then she's nasty and definitely not a friend. You need to tell her off and ditch her. Cances are she thinks she can get away with being a nasty little cow because you put up with her. A lot of people probably don't like her and that's why she's desperate for attention and can only get desperate guys.
