Stupid argument but it's really starting to piss me off!
I can't sleep when it's hot. Even in winter, I like to have the window cracked open slightly so there's a fresh breeze around the room. Our room gets quite stuffy because we have the heating on at the night for the kids, and we don't like coming down to a cold living room.
He insists on keeping the window closed because he doesn't like being cold. Aibu in thinking that's what the bloody duvet is for? He can easily warm up, but I can't as easily cool down in a warm stuffy room.
