Until the affair is completely over and she's actually working on herself, I would consider her to be in the last stages of replay. They go through a period of losing weight and acting out and then they begin to settle down a bit and start gaining the weight back.
I would continue as you have been and observe from afar. No pressure! Allow her to come to you and listen, be patient and listen some more.
You have to remember...we can only go by what you post, i.e., mentioning that the affair is still going on even though it appears to you to be falling apart.
