Oh, seriously, that trip is going to be so much fun! I am so jealous and happy for you all at once. You absolutely deserve a break and a vacation.
I wouldn't worry about not hearing from him yet. I think he's waiting to see if you'll go on the chase. I think you've got him seriously confused because you're not doing it.
I'm wondering, what made him come back the last time? How did you act the last time?
