Wife: "Honey, I'm pregnant and I'm keeping the baby. We need the room and the money so you're selling your toys."
Husband:
This sort of thing is why a non-negotiable condition of any living arrangements I have is my own room, with living together being a duress thing for negotiations purposes. It's my space that I can escape to and deck out how I want - including shelves of Transformers - and guarantees I don't end up sleeping on the couch after late/drunken nights out, or when any Grasshopperettes are down with the flu or somesuch.
