if it's important to you and you're willing to burn social capital on it, just politely ask that he not use it when [your boundaries here].
if you come to an impasse, then there's not much to be done other than part ways. i'd imagine this is similar to any other incompatible roommate situations, e.g. someone whose recent significant other recently started coming over and has annoying habits.
