I don't think you failed? I think you're still in the experimenting stage to see what works. I would NOT look at it as a failure.
I also believe that you will get back to her wanting to talk to you. She's still clearly confused and you will need to step back and let her work through that while you continue to work on you.
There's always hope. That's something that YOU keep alive. Hang in there. I'm praying for you.
