I'd wait until tomorrow and then send a happy, upbeat text daying that meeting up sounds good but you're busy for the next few days. How about breakfast next week?
Then see what he says. In relation to your list on the house sale, I'm inclined to not push to split up your stuff. If splitting up your stuff isn't what you want (I guess it's not if you're standing for your M?), then you shouldn't bring it up. let him do it if he wants to- he probably won't if he's confused or in a crisis. BTW, I think your H could be having a QLC- they can hit at any time from 25 onwards, and if there's an element of serious illness, it could have precipitated the feelings of the fleeting nature of life and compounded things. My H was 27 when his started, possibly 26- hard to pinpoint when the feelings settle in them. MWD also says somewhere that MLC can hit in the 20s; there's not really an age limit, although it is more common in the late 40s).
I also wouldn't worry too much about H not taking his stuff- it's also a sign of the confused mind. I still have 80% of my H's clothes here at home, all of our joint belongings, his CDs, books, camera, shoes, videos, DVDs, his TV. And it's been 10 months since he moved out. The way I see it, he's not committed to being gone, and I'm not going to push him out. Although that should obviously be a personal call to make.
Finally, if you want to sell the house, can you get it in shape without H? I wonder if it'd be a 180 of sorts. The less you ask him to do, probably the better as they really can't stand any sort of pressure if they're crisis-ing.....
Sorry for the somewhat skipping-about post, BTW!
