Heh. Good to know you're makin' it safely across the world.
I'm inclined to agree with RedHeadWife's words of wisdom -- just try your best to "act as if" everything's moving along smoothly ... or at least that you're not afraid of getting served.
I would not, however, send your W a love letter. You are obviously a very loving person. Well, we see that as loving. She, on the other hand, sees it as smothering right now. A letter from you is nothing more than a reminder of exactly what she's trying to escape. It's the last thing, IMHO, you need to do.
As far as the physical question, I think that's mostly your mind playin' tricks on you right now. I can't per se speak to it because when my H left, I was preggo, and the hormones were kickin' anyway. Sooooo, it'd prolly be smart if I left that question alone.
Touch base when you can. I sure hope you're able to access the site from the Stan...
