Great question! Let's hope at least one H has eventually come out of the fog!
From the books I have, I have a hard time finding situations where the H continues the affair and then eventually comes out of it. Most of the examples are of situations where the H agrees to end the A and then they are full of grief and an emotional wreck.
From some of the books I've read, the H doesn't truly recognize what they've done until therapy has started and they start to hear all of the pain they caused the betrayed spouse and see/hear the spouse's anger and sadness. From what I've read, it's really key for both people to go through the pain of telling/hearing about the affair both to start to heal/forgive and to hopefully ensure the H doesn't do it again.
I've been hoping my H may be showing some sign
