If she did that to you, then she's obviously not good for you. I understand how hurt you are (I have a gist of it) and I can just say that, eventually, the hurt will pass by. I'm always here if you'd like to talk!
I understand what you are going through. It's hard to be deceived and suddenly abandoned. The difference is that instead of a best friend, was my father. If you need to talk, I'm here.
If you ever want to have another girl talk I'm always here boo :) & don't worry, you've got me. I wouldn't tell your secrets; who does that? that's irrelevant.
