Second choice

My best friend got a new best friend. At first I was so happy she was making new friends but then she became close with this girl. Back then she told me not to worry bout it she still likes me more than her but it didn’t last long. Now it’s I like u both the same and I know she likes her more. I’m always the second choice. She can’t hang out and cancels on her last minute and she asks to hang with me. The other girl shit talks my “best friend” to me so she’s fake. She tells me she likes me more than my “best friend” when I know it’s just the game she plays with everyone. Anyways that’s it idk what to do tbh
