Facetime, Skype, Facebook messenger, email, letters, care packages, Rabbit (watching netflix, etc. together in a web browser app)...
And taking some time out to enjoy/take care of stuff we won't be able to do once we're together. I'll be going from a spacious American home to a small British one, and I'll have to share space. So I'm trying to enjoy that the best I can now (even if it feels empty).
I'm also doing the back-breaking work of sorting, packing, giving away, and making all the thousands of arrangements of moving overseas.
And, to be honest, sometimes just submerging myself in a book or netflix or whatever, just because I don't want to think or feel anything about the separation.
