Am I in a toxic friendship or is she jealous of me :( ? ?

Im 13 and people usually say, imply and show that i'm a pretty/attractive girl and i have a fair amount of admirers. She sometimes says things like I have a unique face, or your eyebrows are thin, or just randomly say "you're not attractive". but note she's not that pleasing to the eye at all.. I love my friend but I don't understand :(
