Get a book to keep on the counter where he can write down his list of financial and errands he expects from you that week or month. Then he won't be telling you out of his mouth and you won't be hearing his stressful tone. You can refer to the book as an accountability loop. You are reponsible for checking the book to remind yourself when under stress and forgetful. He's responsible for putting those tasks in there that he requests. Less reminding on his part and less forgetting on yours might result and thus less conflict. Maybe?
