Did you send him that e-mail about it being nice to meet up? And did he reply? I guess not yet as you haven't posted about it.
Give him some time- it was quite a big thing to meet up this week, and I'm sure he's processing in his cave. If he hasn't contacted you by Friday, maybe think about sending him a funny e-mail or something (but I'm not sure as you did make contact by sending him te follow-up e-mail).
Havee you read the Time Traveller's Wife? She was always waiting- just like us. Waiting, waiting......
I think doing nothing right now is definitely right, and keeping your expectations low. Yours are SUPER-low! I'm going to take a lesson from you there!
