You're on the right track... You're not alone. You may never wake up your wife (sorry for the pessimism) but I certainly hope you do.
My advice is to remember to take care of yourself. If things start to get too hard to fake it, just get out. Lead by example and hopefully your wife will follow. But don't sacrifice your health (physical or mental) because you think it might give you a slight edge in waking up your wife. In my case I think I would've had a better chance if I'd been up front when I first woke up. It's a crapshoot, so all you can do is try your best and make sure you take care of your needs.
Again, welcome. I wish you the best of luck in your journey!
