AITA...  Long time lurker, first time poster...  Ok here goes, My brother in law is coming to visit for a few days.  My wife decided that in order for her brother to be comfortable, I must vacate my room and sleep in the, as she says "dark, dusty, disgusting" basement.  For context, with the exception of flooring, which is painted, the basement if fully finished, there is nothing wrong with it.  I said NO.  I told my wife how I would be working doubles for the next few days and would need to as much sleep as I can and could not afford to change my routine and achieve the proper amount of sleep. This was unacceptable to my wife and she decided to call me selfish.  Just to clarify, I am a corrections officer, and sleep is the most important thing for me to do my job safely and competently.  Due to my job and its hours sleeping in separate rooms is necessary for my wife and I.  So, AITA?
