I have had a crush on a certain girl for a while now, but I am beginning to lose interest in her, over another girl. Unfortunately, the second girl also happens to be one of my best friends. I know I can't tell her, because she thinks i'm still interested in the first girl, and she would probably get annoyed at me for "switching" so fast. For the same reason, I don't feel like I have anyone to talk to about it but you guys. What should I do?
