So here's the problem. When I and my best friend hangout together she is completely and genuinely herself. I'm the only friend she allows to see her without any makeup on. She talks normal and acts humble. HOWEVER, there's a certain group of "friends" she hangs out with that are THE definition of boujee. A.k.a snobby rich girls. And when she hangs out with these people she acts like her shit doesn't stink, changes her voice, and doesn't speak to me. Like she forgets I exist.  I just need advice on how to handle the situation... please & thank you.
