I wouldn't write him off just yet. He may be considering the situation and hoping he hasn't made too many promises. I think you'll hear from him again in the next 5 days. If you haven't heard in 7 I'd send another message but then no more after that until he responds.
It isn't 'nice' behaviour but I've done things like this in the past and wasn't because I wasn't interested anymore.
