So I'm playing Skyrim, and I decide that I'm going to marry some woman just to get the achievement and have done. I've become well known in Solitude and I think the housecarl appointed to me doesn't look too bad, so I go through with it and get married and we, the happy couple, live in Proudspire Manor. So I say goodbye and go out slaying dragons and whatnot for a while before coming home to drop off some things. It is late at night and I go up to my huge bed. Empty. I look around the upper floors, searching everywhere. Not finding her at all, I assume there must be some sort of bug and wait around the house for a few days hoping to catch her coming and going. Still nothing, so I look around town and sure enough, there she is, walking around. I follow her around all day just seeing where she goes and there's nothing out of the ordinary. Finally night rolls around and she heads home. I follow her into the house, down into the basement, and lo and behold there's a door I missed, in the drafty dusty lower areas with cobwebs everywhere. She opens the door walks inside, and lies down on a pile of straw on the floor and goes to sleep.
At first I tried to reason out that she simply didn't like big soft beds or sleeping next to her husband but then I I had a far more comedic idea. No, my character who always liked to help people out with their problems and forgive people and whatnot was also a horrible misogynist who forced his wife to live like this and treated her like an animal. She's so well trained, she even does it when I'm not at home. I found this concept both awful and hilarious at the same time.
