Everything I've done

Everything I've done, I've done
Only for your love.
Everything I am, I am
In hopes your heart will move.

I know that you love someone else,
But while you're away,
I'll love you just as though our love
Would last till you are grey.

Till you and I are grey, my love,
And all our days are done,
I'll love you just as I do now;
Your heart's my only home.
