Can 1 in a 100 million LDR work? Yep. Do 99.9999% fail for all the reasons already mentioned? Yep also. Its nice to dream and believe and talk about how you both will make all the sacrafices and the plans for the future, but when reality has to be dealt with its another world. You can get to know someone over the internet but nothing replaces being together and unless you have the money to travel often, when will you get together? Its possible but know going into it before you really get emotionally involved that your swimming upstream. That being said, enjoy the dream and keep the hope alive. I wish you the best of luck.
