Como Has Hecho

I should have known that by loving you I was losing myself
I should have known that your world was no longer mine
It's so distant that day when you said
I'm not a child anymore, I don't play with feelings
How have you done to make me love you like this
How have you done that I care for you like this
How have you done, you killed me, my love

How have you done, how have you done

Knowing that my feeling was not reciprocated
I wish to ask you what you have done to me
