WTF IS HER PROBLEM?!?

[Isabel]

So i wont go into detail. My best friend Stabbed me in the back and she lost my trust, i never did anything to her. The same day she stabbed my back i told her i no longer want to speak to her, saying that she lost my trust and friendship. 2 days later she wrote on fb ( someone told me about what she had wrote on facebook for i am not into social media ****). She wrote about me and tried to make me seem like i was the bad guy.She said that i was the best thing in her life and that i lost my only friend. Why in the hell would she want to do this to me? I did nothing to her ever! Why would she want me to be the bad guy and let others think the same?
If you have questions, please ask.
