I don't think you should NOT talk about the R if SHE is the one to bring it up. But validate by saying "its going to have to be different this time if theres any chance" and "I'm not sure im quite ready, I still have some work to do on myself before my changes feel that they can be permanent".
Maybe im wrong, but admitting that your not quite there, even if you think you are makes it feel like your trying to understand yourself and the situation from her point of view? a 180?
Good luck, but don't get down if she cancels either, remember, no expectations.
