Over the years, I’ve had people, some of whom were also in long distance relationships and some who were just interested, ask me how I did it. There is no simple answer, especially because every relationship is different (you know your relationship best). What I can wholeheartedly tell you is it will take a lot of quality communication, effort, trust, and love.
And then one day, you’ll wake up everyday next to your partner just like you’d dreamed of. You’ll live together. Get married, if you so choose. Maybe start a family. All in the same place, in the same city, in the same state, in the same country as one another.
