How often to communicate with someone who is moving away?

I have a friend who I was involved with for a year. I feel far stronger for him than he does for me as I let my romantic feelings linger or rather not fade.

He's moving soon to another state about 4 hours away. I know this will potentially be a chance for me to free my heart but I'd like to maintain some kind of contact as I worry I'll be forgotten. How often is appropriate? What forms? Tips of anything to avoid? How to ensure the contact doesn't drag out my own feelings?
