((Hugs)) Settling into the routine of deployments can be...unsettling.
About one month in I feel guilty when I'm not thinking about him, feel lonely when I do...feel restless at the thought of holidays without him, etc. etc.
I do a lot of writing to him, saving it as drafts in our email box. He can read it when he has a chance, and if he doesn't get to it, I just add more. Mostly ramblings of everyday life, which seems to humor him a lot: the weirdo in front of me at the store, the goofballs at work. The mundane seems suddenly interesting. He writes very little, but that's okay. I think giving him everyday vignettes about life help him stay grounded. It gives him something to look forward to, no matter how simplistic it may seem. After all, isn't the crux of the military life essentially to fight for us to be able to have normal, boring lives? Let him know that at least in your small corner, it's working. His chaos creates your calm. Don't feel guilty about that, because if tables were turned, you'd do the same for him.
P.S. If you can handle the strain of an engagement through deployment, you both have a wonderful, blissful marriage ahead of you! Keep your eye on the prize!
