She did start to hit on a few subjects that involved R and I told her I didn't want to discuss that.
That probably wasn't the place for it, but if she wants to talk about it then by all means let her. The DB 180 tips say not to initiate R talks, but it's OK to let your spouse bring it up and discuss it. If she does then just validate her emotions. Don't agree or disagree, just say things like "it sounds like you are (mirror her emotions back, sad, angry, depressed, etc.) and I can understand why you feel that way." Be a great listener. 80% listening, 20% talking, and the talking should only be to validate and lead her to open up more.
