Long Distance Relationship - How To?

For those in a LDR, how do you deal with the longing? I am in one, and it is challenging at times, because of the distance.
So, the question is: how do you approach wanting to be together all the time? One would have to eventually move – so, how do you bring that up? My SO is rooted, so I would be the one to make the move.
Or, do I just leave it alone, and let things happen when they happen? I do believe that we need to take initiative for things we want. Is this an exception?
