I have a friend that I met at school; we became fast friends because we were in the same class. We've known each other for almost a year, yet I often feel we're not friends at all. Lately she has seemed extremely fake and insincere around me. She's obviously bored when I talk and does not talk to me outside of class. To be frank I would prefer it if we were no longer friends, but I have no idea how to go about it since we will still see each other on campus (it's a very small university).
