I think when you present this to him you should put a list together for BOTH of you... HE needs a list so HE feels safe too...
It's like a contract and you both agree to stick to... and yes the list will be different for you two... there may be some overlap, such as the financials
Yours can have
a. Keep household surfaces clean of clutter b. etc
You put stuff in there you think would make HIM feel safe to continue working with you
