So I'm 14 and I've been friends with a girl since we were 5. We've both changed a lot, but we never stopped hanging out or anything. Since middle school she's been part of the popular crowd but it never stopped us from being friends. She's always posting things on instagram with her friends, but never with me. She didn't even give me a birthday post even though she gave all her other friends one. I know this seems like a little thing but it really bothers me. Do think it's a big deal, and what does it say about our friendship? How do I bring this up to her without sounding weird? Please help!
