Love and relationships are work, I won't lie to you. As long as you both put in the effort (which you will if it is true love) then it will last. I've been with my husband for over 20 years and somedays are easy and somedays aren't but the simple fact is he is the last person I want to see before I go to sleep, the first person I want to see when I wake up, and the first person I can when I have news (good or bad). I know it might sound corny but it's true and I am blessed that he is my best friend (especially since he moved me to the other side of the planet!)
