R,

Until this past April, I was in a long distance relationship for about a year and a half. You've gotten some great advice from the forum.

Here's my added two cents: Don't forget about that antiquated "snail mail". I used to send my former girlfriend a letter or a card about once a week. She would save each one of them and sometimes tape them on the wall of her room. I think it helps them if they're able to see something real and physical nearby that reminds them of you when you're not there. Good luck!
