My old bestfriend and I got in to a fight. I apologized but she won't forgive me.?

She lied about something and I said if she didn't admit and say sorry we weren't gonna be friends. She never did. Then she texted my friend saying blah blah blah you can have Ella I don't want her. Then I sent her a text saying she was a lying b****. Then a few days later I try to apologize and she won't forgive me. And I feel like she's blaming everything on me. I'm scared that my friends are going to ditch me for her.
