I'm gonna go out on a limb here and guess that underlying all of this turmoil is a deep and abiding love between the two of you. Can't account for your dedication any other way myself. So if that's the case, then like you are, I would do all I could to get to the next lucid patch. It's probably going to come down to how well you can keep reconnecting after the next storm passes. It's going to be a lifelong good news bad news situation though. But if you can connect honestly about it enough to be working toward the same life vision so to speak, it could be wonderful. So many of us have been really badly off and through fits and starts, and finally something makes the difference, and "a measure" of stability can be had. Love is the best thing to reach out with and the only thing that will sustain you through the black. Good luck and keep in touch, this might be a really good place for you to hang out.
