All of that is perfectly fine by itself, but does not in any way lead to your staying with him. Tell him that you are really glad that he now knows his real path, and that he is or will be a better man. In the meantime, you will try to find your own path.

Alternatively, tell him that now that you have shown him his real path - and it has taken you close to a decade to do so - you need to move on to other people, who also need to be shown their real path and who have, all the while, been patiently waiting. You stayed with him long enough to show him the real path; you do not need to stay any longer now that you have fulfilled your mission.
