Detaching does come in stages for some of us. It's an ebb, flow kind of thing.
Forcing him to give up the OW, and choose you, will only bring you heart ache right now. Let her be the pushy one. Not you. LRT is your job. Smile til it hurts. Smile even bigger when you want to smash them in the face.
Splitting, even if he doesn't grasp the gravity of it right away ... CAN be the lynch pin to fixing things. Just remember that most of these men come back... lay bread crumbs, don't use a sledge hammer.
