Opinions please!!!!

Okay so I introduced my friend let's say her name is "Cara" to all my guy friends and they were all over her and I was kinda getting upset bc they wernt acknowledging me like they use to . And then they started hitting her up and stop hitting me up. And they said this is why they love white girls. They were treating me like a bro. And I'm just upset over the fact that she's best friends with all my friends now but she hates when people try to become friends with her friends. Plus she tries to embarrass me in front of them . She always has to say something to try to prove me wrong or put me on the spot. I'm just so fucking mad and I don't want to be friends with any of them anymore. I just feel lonely and especially cuz my boyfriend and I haven't been good so I try to hangout with friends to help me get over my loneliness and sadness but I guess not now. SOMEONE PLEASE GOVE THEIR THOUGHTS ANYONE PLEASE!!!!! Thank you
