Friend issues

Hi, I would really appreciate it if someone could help me out with a friend problem I have. So, after Christmas a new girl joined my year and usually my friend (we'll call her E) is closed up towards new people and isn't interested, but she was with this girl (B). On the Friday of the first week back, E met B and you could say 'fell in love' with her... She was obsessed with hearing all about B's life and E completely ignored me for the rest of the day. B is a 'better' version of me: we like all of the same things but she's exotic and has more in common with E.

I have been friends with E for years and I've backed her up no matter what. She's been through all sorts and I've stuck by her the whole time.

E and B became closer and closer which I didn't like as I just found it so hard to like B. But now it's got to the point where E has become 'popular' and is completely ignoring me unless she wants attention or to use me. E acts like she's still friends with me but she also ignores me half the time. She's too stubborn to listen when I try to talk to her about it and I don't know what to do. I just feel replaced and used, and Ik it's probably partly jealousy but that's how I am!

Any advice?
