Here is an article that I found while looking more into LDRs since I recently have gotten into one. The site seems to cover alot of aspects of dating though, but I have not fully explored it. I did however read the article in the following link:

It gives a few good tips on how to cope with a LDR, and i found it pretty informative. Who knows, you might find other info there that you need as well.
