I met somebody on-line a few weeks ago.
He did text you today, not three weeks ago, so IMO, you are still in the game with him. His next text or the one after that could ask you for another date. Anyway, you just have to wait now and see what his next move is.
It's been less than a week right?
Don't rush things....6 hours date is a good sign.
He probably doesn't want to seem to overly eager...he's texting and in communication with you, so I wouldn't worry or put too much pressure on the situation.
