She added me on Facebook...?

[What]

I have sat next to this girl in art class for the the pat few months. We don't talk very much. She added me on Facebook and I accepted. Then she blocked me on Facebook. After a few weeks she unblocked me and added me again. I accepted again. Then she deleted me again. A few days ago she sent me another friend request. I haven't accepted it yet. Why is she doing this? We have a lot of mutual friends and see eachother a lot outside of school but have never talked. I'm also a girl.

Sounds like she can't make up her mind . . . or she's just doing it to torment you. I've got no help for you . . . sorry.
