So i have this loser friend, that I really don't like.?

She is like supersuper annoying. She copies everything that I do, she thinks I'm her bestfriend. I don't have the nerve to tell her I don't feel the same because I don't want to hurt her. I introduced her to my real best friend now she she calls my bestfriend more than she calls me. She called my friend last night [[thanksgiving]] and also called her this morning when she woke up. My freidn is quite annoyed with her too. My loser friend ims me saying she hates my bff I ask why. She says because she my bff always clicks over on her and asks if she can call back. I tell her you DONT HAVE to talk to her. She says she NEEDS my bff to answer. In my head I'm like you don't even call me that much. Even though I don't want her to, what is she doing calling my bff so much. She doesnt even know her. My loser friend seen her 3 times in real life. My loser friend "likes-likes" my bff. Yeah, she turned bi. o.O She tells everyone shes bi. She's so immature. She's the most annoying person on Earth.
