I need opinions on this please! Thank you by the way :)

So, In high school i had always had the same group of friends, but in the last years a new friend came into our group , she was from another school, where everybody hated her, including some teachers, and she seemed nice at first , she was funny and we spent nice moments together, but after some time we began to realise she only liked to talk about herself, she was constantly praising herself , if she got a A , she would tell everyone in the classroom, she even compared my marks, with her marks! She showed off about how she had loads of expensive clothes and shoes , and complained about not having more of them. She also showed off telling us about how many guys had asked her out every week , and how she rejected them , she practically thinks she is a princess, she is pretty , I 'm not saying she is ugly, and I 'm not jealous either , but I really couldn' t stand her . My friends didn' t stand her too , but were to shy to tell her and didn 't want to hurt her feelings . However they started to stand up against her when she said she was going to a much better Uni than us. Now we have finished high school, and nobody talked to her anymore, but she kept talking to me , obviously about the great she is doing at Uni . She even wanted us to get together, but I knew it was only to show off, so I got tired and blocked her on Whatsapp and Facebook , I was done . Now I feel much better .
