Ok....so it has been over a week then. I would say that lack of texting is good for date build up so you have something to talk about and discuss. It also puts him a position of being a little mysterious and since you don't know where he stands or what his intentions are that probably makes you more interested than you normally would be. IMO it all sets up perfectly for an outstanding evening. I assume he will call or text you in the next couple of days to confirm your Wednesday plans.
Most woman are probably going to have sex with a guy buy the 3rd or 4th date unless the attraction levels are off the charts. Most woman will probably start pursuing more after they have sex since they are developing an emotional bond. Since you guys have already had sex I think that is part of the reason why it's hard to pull back and not over pursue.
