You don't have to say anything, just leave the room or house if necessary.
It all depends on what you are willing to put up with. Those things you can't you set your boundary and plan your response for when the boundary is broken. Its all about you. It's not an ultimatum or anything like that. You're not demanding that he behave in any particular manner, you're just preparing yourself for when he is acting in a way that you won't put up with.
Good luck and I hope that helps.
