I understand, Mink, just reminding you that there really wasn;t a change, just a change in what she said, which isn't really a big deal.
Look, there's a lot of thing it could mean. One real possibility is that she was afraid things were going to fast, and she isn't sure enough inside herself that that is what she wants. So what better way to slow things down! Jut remember, you have to take it slow too! I wonder if you got too enthusiastic when things felt better, and scared her off a bit? I really don't know, and I haven't read your thread all the time, so I don't want to guess. So, just get back to basic DBing, no expectations, and see what happens!
