I think it's very unclear what it is you want. I kinda get the feeling that you want to have a R with this lady, but you keep saying you will shut down a R talk because everyone here is saying it's too soon to have that talk. Is it possible that when she says she only has sex in a R, she is really meaning being exclusive? Not everyone has a checklist of what needs to happen to be in a R (some may consider exclusivity a R). Are you the type that likes to date and sleep with multiple people at the same time, or just one person at a time? If you already know what she means when she says R and aren't willing to go there, but you keep hoping for sex, then you are doing her wrong. But if you want to see if this blooms into a R, are willing to be exclusive until you find out it's not going to work, then tell her that and see how she feels about it.
