Did he specifically say he was looking forward to the 3rd date, using the number? There is a "thing" where women will wait until the third date to rule out men just wanting sex, but men know this so just keep the mask on a bit longer, expect sex on the third date and then fuck off.
Either way, the way he behaved after sex was at best thoughtless and unkind, and at worst to make you feel used and a bit humiliated. Do you want to be with someone who makes you feel like that? I'd message him - don't wait around on his time - and tell him you're not interested in taking things further. Take control, and leave him to wonder.
Good for you getting out there. You had a good time and you've lost nothing. Dick is not in short supply, so don't settle for another dick at the end of one.
