I thik this time apart will be good for you guys....you need to learn how to be without him. After I'd been dating my bf for 2 1/2 month, I went to Vietnam for three weeks, and I missed him....but it also made me appreciate having a life beyond him.
One of the most essential things in a relationship is having a life without the other person and being comfortable with them not being there. You said you have lots of stuff to do....so go do it! He's not coming home for two months, so that should give you plenty of time to get done what you have to do.
Make sure that you still make time for your friends and your own personal hobbies while he's home, too. So many people ditch their own lives for their partners, and then when they break up they find that most of their friends are pissed off at them for being ditched all the time for the bf or gf.
Live as if you were to die tomorrow. Learn as if you were to live forever. - Mohandas Gandhi
