Put it this way. You've been fretting about him being too full on so early in the relationship, and you took advice from many on here to gently tell him you'd like to slow down ... not sure if you followed that advice? Now, here you are, having had a lovely impromptu date, and two days later you were worrying that he's not contacted you. Put yourself in his shoes. How do you think he may feel, having taken you out, and had a lovely time, but no follow up text from you to say that you enjoyed it? Maybe he's worrying that you've cooled a bit, as you've not message him ... Maybe you've already done so by now, or he's messaged you, but if not, don't just sit around waiting for him to make the next move ... send him a message to say you enjoyed the evening, and would he like to arrange another night out at some point ... Good luck!
