Rather than "talking" to her and asking her out, etc. Maybe you should try rebuilding what is there. Like slowly flirt with her, but not expecting her to react in any way. Joke around with her and start to have fun again.
Instead of looking at her for physical affection, give her a hug from out of the blue and tell her you appreciate something she had done and kiss her on the cheek, then walk away. Very cool and collected. She'll probably shirk away at first, but you do it very slowly and eventually you'll be able to get closer.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
