I think I would move on, painful as it may be, for real, not as a ploy to maybe get back together someday, or to get her attention.
It doesn't really sound healthy for you. 'Time apart' is not even a relevant term anymore. It's just 'time' now, and it should be spent actually making a new life. And you have to respect yourself, what she thinks or doesn't is her business now, not yours. Please let it go. She made her wishes clear. You are not a human yo-yo, so don't act like one.
Best of luck on your new journey to happiness....
