regarding your question about letting your W know the door is still open -- what about just telling her. A quick sentence or two and let it go. At least that way, you're sure she heard you.
Don't know that it's a great idea, but just a thought.
I had the same idea. Maybe plan out exactly how you want to say it, and leave it at that. If w tries to continue the R talk, and you're comfortable continuing the talk, go with it. Otherwise, move on to something else. Good luck! You will be fine!
