Dazed....the fact that the sight of him "disgusts" you....that is on your side of the street and will require you to manage a way to deal with it....until the agreed on time of actual separation.....
Try to stay out of the house and away from his presence as much as humanly possible....If he really is in outpatient treatment...that should take him out of the house for lots of hours....You could invent some ways and reasons to be away from the house.....
If your emotions are too intense to tolerate that, until the separation date....then, maybe, it would be better for you to exit to a cheap long-term motel...and ask him to help pay the bill....
If you are seeing your therapist, on Friday, ask her to help you with this....
In a way, I suspect that your global anger is protective, for you---away from the underlying sadness and pain of the loss of the relationship....
