Please read this and tell me your opinion?

this girl who i treat as a friend is really weird. sometimes she is chatty and most of the time quiet. she seems to be able to communicate better with others. i text her yesterday and ask if she was angry and she said no. we texted for quite a while. i do tell her about my crushes and she tells me a bout some friendship problems she has with J. however, she did not ask me why i was absent from school today. is she a friend?
