Raine, I'm sorry this happened today. Now you truly need to decide what you want to do. You've told him that you want him out of the house, then he should go. If you go back on what you've said, he'll continue to think that you are just spouting off. You need to decide whether you want him to leave or not. But, whatever you decide, you will need to follow through on it or else, just like kids, he'll continue to do whatever he wants and just tune your rants out.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
