Do you want to meet him? If you don't then I don't think you can say number two as you have emailed him. Maybe number 3 (with perhaps an added snarky comment ). You could say something like thanking him for wanting to meet but you have now moved on with your life and have someone new and you don't feel there is anything left to say.
