I know this feels like a setback, Angel. I remember times when I wished the OW would move back to her home country/get a job in a more distant city/find someone else to latch onto (though how could I wish that on anyone?)/disappear from H's life in some other fashion.
After a while, I realized that if that happened, if it was her decision to end their R, I'd never know whether H really learned his lesson and chose me instead of her. If the choice was taken out of his hands but he still felt the same, he'd just end up replacing her with someone else. And in the end, with the C telling him he couldn't cake-eat forever, he did tell her he'd chosen his wife and family.
Try to think of this, not as the agony being prolonged, but as H being handed enough cake to see if he'll choke on it, or else realize he's had enough cake and wants a healthier option.... And the more you continue to work on yourself, the better you will look to him as an option.
