Don't underestimate the "logistical" reasons for your W wanting her own "sleep space".
Although we have a queen sized bed and CJ isn't really a tosser, he DOES snore ...I CANNOT get to sleep with him in bed with me.
It's far from ideal, but he generally falls asleep on the couch...I go to bed hours later...and he usually joins me in the wee hours of early morn when I'm deeply asleep and less likely to waken.
As for the rest of what's going on with you....I'm JEALOUS!!!
