I don't consider living in denial getting off scott free. There will be consequences, they just haven't surfaced yet.
This disease is progressive, health problems, financial problems, legal problems, relationship problems, are all a strong probability for him, those are the facts of this horrible disease, I don't view that as a very happy ever after, or living scott free.
May I suggest a break? Perhaps now is not the best time to be dating. Sounds like you have some inside issues that need your attention?
