Gucci Loafer's point is good and well taken. I don't think it's necessarily a bad idea to slowly initiate some R questions. She is probably not going to give a straight forward answer to them right now anyway (especially if she is eating up how OIN is serving her).
The caution I would exercise is that men and women do NOT react the same way to this stuff. Men (generally) get over stuff much much quicker. That's why men can argue for two hours, go have a couple of beers, and be patting each other on the back two days later.
Women (generally) can have a vivid memory of something that ticked them off 5 years ago and not be past it yet.
That is why it is USUALLY (not always) better for the W to bring up the R talk, because it probably means they are in a place where they can do it without blowing their stack.
