Boy dates girl turns out shes crazy, has brothers that were on football team, attacks him with a ski set at a party

I read this book around 2008-09 in elementary school and now its been bothering me for a long time. Boy was dating some girl and its kind of a generic yandere type of situation but was, as far as i know, an American book. Horror about the girl being crazy and the boy trying to date some other girl but one of the scenes that really stuck out was i believe it was his birthday party or something and someone got him a ski set and she attacked him with it and she had bothers help her kidnap him? It was a paperback book with a page and bloody writing on the cover (and a rose i believe?) and mostly if not all black. This book was in my school library. Its really been on my mind so any help is appreciated. Thanks alot.
