It is definitely business now. As for the relationship w/ her, to quote my good friend SirPrizeMe, the flame is definitely flickering out. I also think she's showing her true colors and there is little to no hope of her ever looking in the mirror and taking responsibility for who she is and why she's unhappy. I'm pretty sure she'll just live the rest of her life blaming me while I'm rebuilding mine and living happily.
I'll go mostly dark from here on out. I've already responded to her today and I did add more than I needed to, but now that I've read your suggestions, I'm going back to the dark side.
