i think my best friend hates me. what should i do?

ive been friends with my best friend for around 2 years now and im starting to get the feeling she doesnt want to be friends with me. at first I thought I was just going crazy, but I feel like she just isn't that enthusiastic around me now. recently shes just been acting really off and mean, and i dont know how to bring it up. i feel like sometimes i can be overreacting, but i really dont know what is going on. it started around when we went on a double date, and ended up talking to two best friends. It was good and really fun at first, but then it started to feel weird, especially because she was just with this guy for his money. she would constantly talk about how he looked bad, and how shes only with him because he owns a mansion (btw he wasnt even that bad looking). then when we went on the double date, she tried to make me pay for everybodys food when i openly expressed i didnt feel comfortable doing that- i ended up paying for all her stuff, keep in mind she has a job and i dont. she would always talk about him, and i would tell my other friends i didnt like how both of us acted when we were with them. i couldnt find a way to express my opinion so i just kept it in. safe to say that didnt work out, but i kind of feel like she isnt over him. we constantly talk about him, but recently she found out hes bringing another girl to prom and that he wouldnt go back to her. after that, we would hang out, but it wouldnt be the same. she would treat me different in front of our guy friends, and suddenly switch to their side if we were ever were debating something. shes made a couple of racist commetns towards me (im asian) and i feel like shes constantly comparing us. i dont know how to express my discomfort since i know she will become mad at me if i do. ive tried distancing myself, but that just ended with me getting ignored and given the silent treatment. just today i mentioned something about the double date guy i found out because i thought she would want to know and she acted like i was still obsessed asking why i care so much and that the guy i talked to just played me and im too stuck on him to even notice. shes made commetns about me not being over him multiple times, and its gotten to a point where its honestly uncomfortable and ive told her repeatedly that i am over him, but she obviously doesnt believe me. another thing is i have a feeling shes talking bad about me to other people. i have no proof, but she talks bad about EVERYONE, including some of her best friends. once, we had a sleepover and she called a guy and trash talked all their friends commenting on how all their social media posts were bad and screaming and laughing while i just sat there- also note this was the middle of the night and i could hear her throughout the house while everyone else was trying to sleep. i repeatedly asked her to quiet down and she refused. this has been a pattern. she says the n-word, r-slur, and f-slur (shes white) and ive expressed how not okay that is but she claims "she can say whatever the f*** she wants". she also likes to just plain call me stupid and the r-slur sometiems and i have no clue what to do. half the time i eat lunch with her, its me starign at her while shes on her phone and trying to make conversation. she never makes any effort. shes always ignoring me on snap and tiktok, and she never reaches out to me on any platforms. i feel like shes only friends with me cause she feels she has to- shes repeatedly said that we have no friends and we only have each other. i constantly feel like i canr even say anythiing without being called a name, and shes always getting upset with me. if i tell her something exciting, she'll usually just respond with a thumbs up and not care. once, i got to lunch early and got lunch without her, and when she found out she called me a motherf***er and drove off, leving me to eat all by myself. shes also called me insecure to her talking stages and has used my experiences to make more conversation. once, she stole my phone when something happened to me and then took a ss, sent it to herself, and then sent it to a guy. once, i set her up with a guy and she refused to add him back on snap cause he was"ugly" (imo and a LOT of other people hes very attractive). after a bunch of convincing she added him back and liked him because she thought he looked like matthew moore- didnt even bother to learn his name btw. i had a good pic of him she wanted to send to her friends, but i didnt want to because it would notify him i sent him, and i thought it was an invasion of privacy and really weird. she then proceeded to get mad at me and ignore me till i apologized. once i asked to borrow 5 bucks because i lost my money and needed to eat and offered to pay it back, thinking it was fine cause i would pay her back and i pay for all her stuff. she then said absolutely f***ing not and that i was poor and she would never give me that. i dont want to sound mean, but im pretty sure my family is more sucessful than her, so it felt a little weird for her to say that to me. theres been a lot more instances like these, but ive felt like ive said enough and i have no clue what i should do. if i stop being friends with her, i wont have any really close friends and idk what to do. help anyone?
