I agree with Nelliemoser. It sounds like either an anxiety disorder of some kind or some sort of spectrum condition. You will probably make it worse if you don't go along with it.
It might be worth doing a bit of research online as to what causes his behaviours (with the usual scepticism about online information) as you may find some advice as to how to deal with it. Most people don't micromanage to this extent so I feel that you will probably need to give him the benefit of the doubt and think about how difficult it must be for him to be that anxious all the time.
