What might be a rather simple [but blunt way] to get some idea is to ask him 2 questions. How much "stuff" does he have and how long does he usually stay dressed.
There are so many Forum MYTHS that abound here. The most important thing is to not fall prey to ANY of them and EXPECT certain behaviors from him.
The spectrum and variety of all "CDers" is endless because all CDers are Humans and all Humans are unique.
I also think it's important not to just simply grab his hand and blindly jump in with 2 feet.
EDIT: btw, you are supposed to be "mad" because he lied to you. One of many Forum MYTHS.
