Please don't worry about the stage he's in. The stages are just a guideline and nothing more. Try to remember that those stages are not linear, but they bounce back and forth in them.
Maybe he hasn't mentioned divorce because you've backed off and just left him be. I would continue as you have been, i.e., living your life to the fullest.
If you want to test the waters, you can wish him a Happy Holiday when the holiday gets closer...but nothing more. Treat him as you a friend and if he responds, then fine. However, if he doesn't, well then, chalk it up to something that isn't going to work and continue moving forward.
Keep the focus on you and leave your h in God's hands.
