Just another option I guess

So my (old?) friend group consisted of mostly guys (I'm female) and my best friend who was also female. The boys over the years have become more toxic, excluding me & my best friend (who I'll name tiffany, not her real name), calling us "cringe" if we acted like girls or "e-girls" or didn't go along with their crappy humour and jokes. Anyways, Tiffany is now friends with the 'popular' girls at school. She said she left our friend group because it was problematic and there was so much drama, which I never understood since the popular girls are WAY more problematic than our nerdy gamer friend group. School started again this week for me, she didn't return, which is fine ofc. But we haven't talked in over a month. Since very late last year (Nov-Dec?) was when she started hanging out with her new friend group, but slowly she's become so much more distant. We had a talk over a week ago and she said she was scared to talk to me because she thought I was mad at me blah blah... Haven't talked since. Please note I HAVE talked to her about this, about how I feel like she's drifting and doesn't wanna be friends anymore and I'm not important to her at least a couple of times since Nov-Dec last year. We've been friends since the start of high school and I don't want to lose her but she's treating me like another option to her if she loses her friends she has right now or gets bored of them because I literally get no contact from her anymore and I've given up trying. I'm not pretty, nor cool like the girls she hangs out with and she's changed. Her ex-boyfriend said the same, that she isn't the same girl he knew when they started dating. She doesn't think she's changed though. She's way more financially stable than me and I remember this conversation we had a bit ago. We were joking around about what we've done for each other and I said, "what about all the love and things I've helped you through and vice versa?" and she just said, "what about all the gifts and things I've bought for you?" and it hurt so much hearing that. Towards the end of last year, she'd only hang out with me and always ask for my food because she'd "forget" every single day, which doesn't make sense??
I feel like cutting her off completely and just removing her on socials because there's no point if I'm not talking to her anymore. She has better friends now and that's fine, but I wish she'd just tell me the truth and tell her that she isn't interested anymore or something. I've also wanted to cut the guys off for ages because they never ACTUALLY care, and they've never cared. I've helped them through so much but whenever I've tried talking to them if I was down they'd shut me out or never check if I'm alright. They only ever really talked to me if I was around (recess and lunch) or if they needed advice from me.
I know I sound hella selfish but I really am just sick of being treated like another option. I just want some true friends who care about me and accept me for who I am and have similar interests instead of being insulted and called cringe every 2.5 seconds.
Thank you for letting me vent here.
