Why in the world are you with him? You can't stand this guy, every thing he does and says drive you up the wall - to the point of throwing a bottle of expensive cologne across the room at him.
I think it's completely normal to plan what you will do tonight, by mid afternoon. I think almost everyone knows, by mid-afternoon, what they will be doing that evening, if they are a couple. At least a rough sketch - going out to dinner, then home to hang out. Something like that.
I don't know why you spend any time with a man who irritates you so much you can't stand to be around him or even think about him.
He sounds way too dependent, could be a real drag in a long-term relationship.
It sounds to me like you are getting tired of him. He's getting on your nerves. I think you are already stepping out of this relationship in your mind.
Just tell him to surprise you. Tell him to pick what yall do and surprise you when you get home.
