Then maybe the best thing would be to write to INZ and say that you have only now been made aware that as you haven't lived together with your fiance, he doesn't meet the requirements for partnership, so you will have to remove him from your application. If you voluntarily give this information yourself, nobody can think you made a fraudulent application. There are many people - we've seen them on the forum here - who misunderstand the INZ definition of partnership, as it's different from in their home culture, so you would definitely not be the first to have to admit this problem. And you would not be blocking anything for your fiance. He definitely would have no chance of getting Residence along with you on this present application. But the fact that you have given his details as your fiance now means that any future application he might make, if later on he spends some time living with you and you sponsor him for a partner-sponsored work visa, has a better chance - his relationship with you will be on official record.
