I have done this a little, but, admittedly, have not asked her "out" again for a few weeks.
I do think I should try drawing her closer, and maybe she brings up the R discussion.
I don't think she will be overt and say, "Hey, I'm ready to talk about us." I think it will be very subtle. Likely, I think she will just open up enought to walk me down the path of having that discussion with her.
