Wow that guy sounds super shady! I'm really sorry you're having to deal with this, I would definitely not being paying for 8 people if only 4 are going to be there, especially if it's not in a contract! You definitely want to get a contract worked out with him so that he doesn't start changing more things on you. I hope everything works out and that he won't be there monitoring your every move on your wedding day, that's weird that he lives upstairs and conveniently left that part out.
