Please remember! This translation is my personal work It is sometimes difficult to translate word for word from Spanish to English, so it may sound awkward in one languange when it is perfectly natural in the other But I think you can get the general idea!

I am the one who loved you
when you needed love
I am the one who hugged you
when you were hurting
And now that I need you
I can't find you
Maybe everything has changed
Maybe you've forgotten me
But I want you to remember
that you were always everything to me
I was the one
who thought of you every moment
I was the one
who watched you walk away
I can't understand why you left me
I can't understand why you hurt me
The pain doesn't matter
You are still my love
