I am. Different countries coming up on 5 years. Planning on another couple years until we are both FIRE, or sooner if he moves back to his house in Phoenix and I can go spend the winter there again (not keen on spending the winter in NJ, and also his living situation there makes it prohibitively expensive for me to do so).
We are both very independent and have our own goals and dreams, so even after FIRE our living situation will be very flexible, but together more often than currently and hopefully more often than not.
Travel costs used to be higher at the beginning with shorter trips more often. Now we usually do longer trips less often. Credit card points help, but it's not as easy to get good deals in Canada. Due to the distance, driving or meeting half way would end up costing quite a bit more. Sometimes we meet somewhere else completely if the cost is right.
Being able to work remotely or take leave of absences helped too, to spend 4-6 months together at a time (happened twice so far). Ultimately it costs more, but it's important to both of us.
