I still have all the letters my DH and I exchanged when we were living on opposite ends of the country for the year before we were married. And it was before e-mail, so it was snail mail all the way! And long distance was expensive so we only talked once a week. It is quite fun to read over all those letters - some of them 18 pages long! My husband's landlady said she loved seeing the letters in the mail, big thick envelopes from me arriving at the door. On our 10th anniversary, I bundled them all up, put them in a special box and "gave" them all to my DH, with a new love letter. No other eyes will (or should not) ever see our letters, but it is such a special thing to have for the two of us.
Still, being separated is horrible. And after that year, we never did it again. the longest we have ever been separated since, is two weeks, twice. So chin up Carrie, you'll live through it and when you look back on it, you'll say "Yep, that was horrible, but now we have some nice letters as keepsakes!" Glad to hear he's doing better though. It'll be September before you know it!
