So I have had a best friend since about 4th grade(im in 8th now) and we've been bestfriends since. But today she's ben acting really different. She's been ignoring me and when she talks to me she does it a really mean and snobby tone. I have asked her what's wrong and she keeps saying "nothing, ok?!?!" in a really snobby tone. After the class we had together she wouldn't talk to me and she usually waits for me while we stop at our lockers, but today she just walked right past me and ignored me when I called her name and I didn't see her for the rest of break. I asked my friends if they noticed anything and they thought it was because of this girl she started hanging out with. We found her at lunch and she was sitting with the other girl laughing so when we sat down next to them she completely stopped and turned the other way. We tried starting conversation but it didn't work. She eventually said she wanted to spend time without us and with other friends and thought wede understand but how could we know that if she was completely ignoring us? She was sending off the wrong message is all I'm trying to say, but continued to be mean the rest of the day. It seemed more like she was trying to get rid of us then spend time with other friends. I don't know what happened just a couple days ago she told me she wanted to spend more time with me and now she's trying to get rid of me?
Sorry this is so long I just don't know what to do! PLEASE HELP!
