Just a lease is not awlays enough to prove cohabitation. Financial comingling, shared bills responsibility and other evidence may help.
 
USCIS may not know for sure whether you live together or don't. That's the whole point of RFE.
 

Hi! any updates? how did your interview go? 

Otherwise yes, submit everything, don't skip the months. From the beginning of the marriage to the end.
 
Photos, if you have many, select one or two from each month throughout marriage. In a Word document, place 2-3 photos per page with annotations (date, people in the photo).
 
Maybe would be helpful to write a cover letter too briefly explaining the situation.
 
Did you have any joint savings account? I know you mentioned no joint checking. Maybe throw in club memberships if any, family Amazon / Netflix accounts. Maybe take photos of your place from multiple angles showing your living arrangement together (don't include it, but have just in case for the future). Include USPS Informed Delivery emails showing letters to both of you if you have it.
 
Good luck!
