It is said that "pure gold becomes more pure by burning in fire". That is what happening with AR.
Their true love is passing the burning test of time. Their undying feeling for each other is becoming more evident to the world with each passing day.
May be they are not together now, but still today they feel for each other, their heart beats for one another.
This break up has shown another shade of their relationship. They are separated due to various causes but their hearts are still together.
This break-up shows that they are together still now, though they are not together in the eyes of the world.
Now I feel the meaning of "Dill Mill Gaye".
