He wasn't confused because we slept in the same bed. At the time, we both knew that it was way too early to get to the next level. The confusion bit happened a couple months later, in a different situation. Actually when he was confused, I was too: we both felt that the time was right, but external reasons were stopping me from "giving in". That's why it felt "wrong" (to both of us): we still wanted the same thing, which was to have sex, but didn't get it because of external reasons (which we also got over through communication).
Anyway, the point is that during the first month and a half of our relationship, it felt perfectly right to sleep in the same bed without having sex - because we both knew what we wanted and we knew we wanted the same thing : ).
As I said, unless they had previously discussed it, the OP's date had no reason to take offense. Pretty much anyone would have thought that they were about to have intercourse, in a similar situation.
