This song expresses the art of letting go. When its not working out well anymore, someone has to give up and give the other one freedom. It's about realizing that even if you give everything that you have for the person that you love, when he/she doesn't feel the same anymore, you have to accept it and you have to let go. You shouldn't hold on to someone who's not gonna hold you like the way you do. You shouldn't keep someone who's not gonna stay with you forever because if someone doesn't want you in their life anymore, whatever you do and even how hard you try, you will never feel it's enough and worthy at all. In the end, you have to make a choice, you have to let go and you have to ACCEPT that not because you love someone deep and you give everything to him/her, you'll have that person for the REST of your life. After all, love is about sacrifice, letting go and ACCEPTANCE. As they say, if you love someone, you should learn to sacrifice and if you love someone, you should make him/her happy. So if that person doesn't find happiness in you, let her/him find her/his way to happiness even if that kills you a thousand times. "Letting go is the BRAVEST thing someone can do for the person he/she loves the most."
