Sounds good.
How about: "SO, I will no longer be more into an R than the other person. And, I am not interested in a casual or nonmonogomous R with you. So, leave me alone unless you are serious about something with me."
BTW, don't forget the easy test -- did you feel good after he stayed over the first night? My guess is NOT. NOT = bad idea.
