I think she's more interested than she lets on, and I can't see anywhere where you blew it. So you persued her, but she wasn't exactly kicking and screaming, was she? And she knows you love her anyway, so you're not telling her something she doesn't already know.
I know with DB'ing we're not supposed to pursue and most people I say don't, but your XW responds to you most of the time so I think your case is different.
And if you want a bit of space from her, fair enough.
