Letting go isn't giving up,
It's accepting that it wasn't meant to be.
Sometimes, it's better to let go instead of letting your heart die in front of your eyes.
We may not be the same 2 people, but we can't deny that we were the best of friends.
But once you let go, you know you did the right thing. You know that neither of you are suffering. You know that both of you are happy.
