Breaking up doesn't mean to stop loving someone. True love never depends on a relationship. True love doesn't care about what you'll get in return. It cares only about how happy your loved person is and will take you to great lengths to put a smile on their face. True love has zero expectations from the person you love. You can say "I love you" and never hear a response and still be fine. Loving someone doesn't mean to convince someone to love you back. It only wants to see them happy, content and full of life.
True love can make you let go of that person just because their future will be better with someone else and you hope from your heart that they do find that person. And, if by chance, you are that person yourself, you will go at every lengths and heights just to make their life best.
Love is not relationship. Love doesn't depends on likes and dislikes. The most incompatible people can be deeply in love and not in a relationship at the same time. Love, at its virtue, is never complicated. It gets complicated only when expectations come along.
All in all,
True love is one-sided
