Is my friend jealous of me?

we been friends for 6 years but when we're around other people. She acts so rude towards me. I have noticed a lot lately, the things I want or wanna do. She goes and does that same thing. One time I wanted to do yellow nails and she told me it was ugly. I did my toe nails yellow anyways because I don't care and then we went another nail place and she said she's gonna do yellow next time -___- or how I do this cute hair style. It's called a half up half down its from the 90s and I have long bangs so I keep them out and I seen her doing the bangs out like me and she never does that. Or I had an outfit and she copied the same outfit as me just different colors. And she tired to make fun of me in front of other people ..... Is this jealous or is she weird friend?
