I'd want one that says, "pain in the ass to live with. Full of
   quirks. Needs PLENTY of space to do projects and hates being
   smothered. Might cuddle now and again, I dunno. Like to pretend
   to be a loving couple in public but at home wants to be left
   alone unless necessary. Won't bother you either but I'll be
   civil and pleasant and nice when I do and I expect that out of
   you as well. Likes to talk about whatever I'm obsessed with at
   the time and will gladly listen to yours too but I might call
   you out on bullshit as long as you call me out on mine sometimes
   - just not every time, ok?" Some thing like that. Me.
