"HELP ME TEENTALKERS"we were friends before but not best of friends

so here's the story.
there's this girl who's a part of our group && we really treat her as a part of it,even showed her what a friend really means. i think we got overboard by being so kind and after a while, she said she don't wanna be a part of our group anymore. we set her free and said apologies for everything that we'd done wrong. whatever it is just to agree to her decision of leaving us.
she think she's being used by us because with all her fancy && glamorous things, she considers herself on a pedestal cos of all the family money and social status [which i think is average only compared to those who were really wealthy]. when she was allowed to carry their family car, she starts to put gap between our group and herself. she even told me personally that she wants to start hanging out with those girls who also had their own cars so when other people saw them on a gimmick night, boys would drop their jaws to see this chicks with their wheels rolling around,. i really felt bad about it knowing that she would leave us for all those stuff coz we dont have it.
after that, we we're hearing rumors about us saying that we are "social climbers,trying hard users.. and all those meanies." we we're shocked about this issue roaming around our campus coz we prefer to be called 'cowboys' coz we know how who we really are and what were we even before she digs in. we preferred to be called cowboys because even though we were kikays @ heart we remain to be low profile chicks. yes,our group knows how to carry ourselves properly but by being seen as trying hard chicks coz of the way we dress? so unfair. we were even told that we were storytellers while she's the one who's telling all those stuffs that we 'envied' her cos she's pretty,cos she had those wheels and those high profiled chicks who she hanged out with as of now.
hearing these typical lies and stories we really want to confront and ask her what the real problem is but she'd never talked to us. we were really disappointed about her. we wanna talk to her cos all of her friends starts bugging us cos she her new set of friends that we were the one making all these stories. they're even giving out death threats and all.
knowing that we were friends before,we know all stuffs that could destroy her but me and my girls promised not to be like that and step on her level. it's really hard for us to make a move. we really want her to be the same girl we knew before,the one who's simple and not hypocrite.
what am i gonna do with this kind of scenario? cos we still hear threats from everywhere
we knew it's her happiness to see us begging on her knees
but that's one thing we'll lose for her --our pride.
guys please help me. what should we do to make those hypocrites stop?
