What can i do anymore?

I know how jealousy can be. The truth is you can have more than one best friend. Just because she is best friends with the other person doesn't mean she can't be best friends with you too. It doesn't matter when you guys met. I know people can become bff's after they meet in a month. I had known a girl since I was little and we were bff's, then when she got older she met another girl that is now her bff. It's not that big of a deal and just have fun together you don't have to label your friendship!
