MY friend has changed for worse

I've been friends with this person for 6 years now. She used to be the kindest, most caring person I knew. Early into our friendship when I told her my beliefs, she wasn't judgemental or anything, just accepted it. However, after graduation, I noticed she had changed drastically.

Just a few days ago, she tried getting me to play an online game with her and one of her friends that were part of a group (not gonna say right or left because i already get hate for it). Shes only known this person for a few months, and not to sound cringe, but i think they are a big reason why my friends changed.

When I said "you know I'm against that stuff" and claimed that being around those people made me uncomfortable, she acted like I had said it for the first time. She said "well sorry I decided to grow a pair and follow my own path." No kidding. Word for Word, lmao. "I need time to think about whether I want to stay friends with you or not." It's been almost a week now, and there's been no reply.

I know it's bad that even though she treats me like crap now, I still want to be with her in hopes she will change for the better.

Is there any advice someone could give? I know you can't exactly change a person, but I don't want to lose hope.
