Amor Ate o Fim - Love until the end (english translation)

Gilberto Gil's music and lyrics. Dedicated to the memory of Elis Regina Carvalho Costa (1945-1982)
Amor Ate O Fim

Thank you fabricioooo for the brilliant translation:

Love doesn't have to end
I want and I know I will stay
Until the end, I will love you
Until life in me decides to fade away
Love is like a rose in the garden
We take care, we look (* like taking care...)
We let the sun touch it, so it can grow
The rose of love always have to grow
The rose of love won't unpetal (*I don't know if this word really exists but that's what that means: losing petals)
For who take care of the rose
For who knows how to cultivate
Love doesn't have to end
Until the end of my life I'll love you
I know love doesn't have to
Love doesn't have to *(fading rapidly 'till it ends or something like turning off the light, the same word as the 'fade away' I've used before)
Until the end of my life I will love you
I know that love doesn't have to erase
