Do you think im right or wrong?

your not a backstaber, but im kinda lost at what you question is here... are you trying to figure out why she thinks your a backstabber? well maybe its cuzz the best comeback at that point was to call you what you called her, make sense? i think she is just jealous that her friend liked the same guy she did and since someone else wants him now, she has to have him back... the whole if i cant have him nobody will thing
