Maybe to clarify would R talk be more like "can't we work it out" ETC.
Where as this is where are you at?
Let me put it this way. Asking her to clarify the "what happens in the bedroom stays in the bedroom" comment is not necessarily R talk, but it can easily lead to R talk.
It sounds like she's trying to articulate some kind of boundary, and you will show her (and yourself) respect by clarifying exactly what the boundary is. Once it's clear what she meant by it, end the discussion.
