Ingeborg, on the good side, as your husband progresses through treatment he will feel worse and hopefully won't notice or care about the little things in life such as a house not picked up, etc.
Good luck in the weeks ahead, if he gets nasty have him go into another room and close the door. Soon his throat will be too sore to yell.
