What meds are you on? If they're just daily meds, what's the problem with him having them and giving them to you? If you take some PRN like valium or painkillers then you definitely need to be able to get them, but those are also the top choices for suicide (even though benzos have an incredible safety margin on their own), so personally, I'd think you should probably only have 4 doses on hand of that sort of stuff at any single time.
I have to take lots of meds daily, but recently I had to give them to my fiance so I wouldn't take more than I was allowed. That's still a struggle I'm facing and probably always will. I have to take 11 to 13 pills per day minimum, and they're all doled out to me at their appointed times and well hidden by my fiance in rotating locations throughout her "bedroom" in our appartment (it's more of an extra storage room since to keep her parents happy, we pay for two rooms).
I guess if he isn't withholding meds, it's a great setup, but if he ever withheld your daily's (not simply restricting prn's), you'd really have to re-evaluate things.
I find it hard for me to find any fault in the guy for not wanting to go out and do a ton of research. I went through the same thing with my fiance, and now, I realize it was kind of selfish of me to bug her about not researching. I mean, it's not her condition, and for me to force some new responsibility on her all of a sudden- according to my timetable- was wrong.
I did the whole bring-her-in-for-a-meeting-with-a-doc thing, and it didn't solve anything. I don't think she's did any internet research on bipolar disorder in her life- but that doesn't mean she doesn't know what to do. Frankly, for a partner to be supportive and know what to do when, it doesn't take a whole lot of reading. It takes experience- and that takes time. You need to relax your demands and just accept what he's willing to do as he's willing to do it.
Today, my fiance is super good about knowing when I'm about to become depressed or when I'm becoming manic. She's learned all of the warning signs through experience not a book.
Experience is the best way to learn these things- but unfortunately it's not the fastest and situations may, and probably will, arise where he really ought to have known something but didn't. You can help him learn these things.
Him not wanting to research it on his own is no reason for you to stop communicating about it. Or about anything. You need to let him know what you're learning that will be most relevant for him in his new job of "night watchman" (ie- your first alert and warning signal). He's able to let you know when things are going wrong if you're just able to let him know what to look for. As time goes on and you have some mood swings, maybe even a full-blown episode, he'll learn a lot and be able to tell you things you won't even notice, but for now, just keep talking to him and let him know what you know that will be most relevant for him to be a better prepared radar.
Continuing to communicate is important no matter what. If you can't talk about this, your marriage is definitely going to suffer.
