As far as the affair fog, stop fixating on that. It doesn't matter. Some lying cheaters (and she IS a lying cheater) come around and break through the fog. Some never do. I know a couple of people that cheated, left, eventually married their AP and remain married until this day. This is very rare because if they'll cheat with you they'll cheat on you. But for some the affair fog is their new reality. You keep mentioning it like one day soon she will wake up and boom! The fog will be lifted. That is a terrible thing to put your hope into.
Affair fog. No affair fog. None of it matters. You need to be stopping all pursuit and pressure (including MC). You need to be going out and GAL. You need to stay in IC to deal with your own issues, 180 on bad behaviors, and become the best version of yourself that you can be. And you need to DETACH! Stop letting her words and actions affect you emotionally. And for crying out loud, STOP talking to her about all of this. You mention talking to her about the affair fog. REALLY? That is like confronting a heroin user once they are already high.
Read DR. Put it into practice. Move on without her. Eventually she might come around. Likely it will be after you've already moved on and no longer are waiting for her, but that will be her loss.
