It takes hard work and a willingness to be open to various types of communication. You don't have physical touch so everything else is really important. Ideally everyone knows what everyone needs out of it and there is a willingness to try. Its even more important all sides are invested in the relationship. Otherwise you can end up disconnected. Without that physical ability to reconnect, it can start to spiral.
LDR's aren't impossible but they do require some alternate thinking when it comes to how relationships evolve.
It sounds like you have the right attitude. Best of luck
