IMO, don't try to talk her into anything, or remind her of the good times, or try to get more reasons behind her feelings. It does no good. Reminds me of me in the earlier part of the year when I was pursuing my H and reminding him we have so many good things to build on, yada, yada, yada. I almost cringe now how pathetic I probably sounded. From what you wrote, I think in her mind the romance has worn itself out. Sorry, but that's how I see it.
