LDRs are only workable if both parties (those living away from each other) are on the same page as to what they want from the relationship.
I personally, don't mind LDRs at all. In the past, they have proven to be interesting. I once dated someone (albeit a pilot) from Oregon, USA, while I lived in Ontario, Canada. What a great time that was. We had similiar hobbies, and enjoyed each others company quite a bit.
There is a bit of a conundrum when it comes to successful LDRs. You have to make sure there is either an end-result goal, e.g., "We will be together in X amount of time; we will work towards that timeline," or a series of mini goals, so that the relationship progresses over the long term, e.g., "We won't ever live together, but our goal is to see each other every X weeks or months. Here is a plan, lets make it happen." At the same time, you must have very few expectations.
If you love something, in an LDR you really do have to set it free. People tend to have restrictions on one another out of fear of losing them. In LDRs, that's usually a sure-fire way to lose someone. They can`t have you, due to distance, but they can't have anything else either, with high expectations, and fear-based rules in place.
Does this mean you don't have anything in place to safeguard the relationship? No, of course not. But those safeguards should be from a 'meeting of the minds' place in life, where you use the things you both already agree on, and run with that.
Not impose stipulations on each other.
Nobody wants to say it, but resources ($$$) must be available. You need not be rich, but you do need the ability to earn money, and tuck some of it aside so that visits can be kept on schedule.
Those are a couple of things off the top of my head. Good luck.
