SLAP!! (lovingly!) Pull yourself together girl!! Ha ha!!
Pick up the phone, dial his number and see how you go. The more you think about it the more tense you will be.
Just do it baby!
Its totally normal for you to be catching up now after 5 months. You are just calling as a friend, and you want to hear the very basic outline of what he has been doing.
Seriously just put on your bright fiendly voice and pick up the phone and say hi! He wont be scared or pressured, cause you are just thanking him for returning the key (dont gush about this too much though - mention it once and move on).
If it goes to voicemail then leave a message, but it is SO much better to have a little friendly conversation. Let him do most of the talking and eave it on a positive note - like 'good to talk to you', so he feels comfortable to call you another time.
This is your big chance to put your knowledge into practise. And I know you know what to do. You will be great! He will be happy to hear how happy you are!!!
(Forget about the gifts, they are your back up plan for a few months time when you are connecting more frequently)
((((T)))) (He's going to be happy and suprised to hear from you!)
