I think you need to push her to open up to you regarding her feelings. Something isn't right by the sound of things. Maybe you both need to go to therapy? If she knows, you know, and is still being distant about everything somethings quite wrong. The hope of a cuck confronting a wife's affair really is usually to get her to just start being honest and sharing her experiences. The hope never really is to stay tight lipped. My opinion of course.
