Hang in there. :/
I'm hoping that, in a few month's time, when I'm in your shoes, I'll be too busy with the visa process, and packing and spending the holidays with my family here to be overly distraught that my shiny, brand-new husband will have gone back to Scotland. After all, he's only coming for a few weeks, so we won't really have had a chance to start our 'real' married life together, and be used to having each other around 24/7.
I'm also hoping (very hard, because at this point, who knows?) that we're only apart for a couple of months at the most.
And I'm trying hard not to let myself freak out too much about what I'll do once I get there. But that's easier said than done, as well.
I guess my strategy is to just try to focus on the good stuff. All the things we're going to get to do once I've moved. I try not to think too hard about the actual details, and just let my brain go fuzzy with joyfully oblivious anticipation.
