Your answers could affect my life for a month!?

I'm leaving tomorrow for vacation in Europe. I'll be with my family and I know I'm really lucky and excited, but my boyfriend and I are in a really great relationship and I'm really going to miss him. I'm going to send him postcards and if I can find a computer, send him emails. Since we'll be overseas, I can't call him. How do I enjoy the time away if he's always on my mind?
