I am in the early stages with my WAH. I avoid R talks like the plague (I agree with Tomato that relationship talk itself is not a plague, but it is certainly anathema to saving my relationship at this stage). Why on earth would I invite him to remind me that he does not want to reconcile or that he no longer is in love with me. The moment I told him I accepted his decision, he stopped telling me how happy he was to have left me and started telling me how miserable his life is.
I am glad to avoid this subject with him altogether for the time being.
