Sort of sounds like an ultimatum. Sort of. The definition of an ultimatum is a demand which, if not met, will result in some serious consequence.
"You will do this: ________________________, or else: ____________________"
You have no "or else".
I can't say if an ultimatum would even work. And I can can see from your later posts that you don't want to leave him, or kick him out, i.e. issue a consequence. But contract or not, there is nothing in your request that will force your husband to comply with your wishes.
I second you visiting our friends and family section.
