Analysis of This, I Promise

Once you've asked: how long will stay beside you?
The sun will rise and set not my love will melt
Dusk to dawn shall come this still say-
Won't live a single second without you.

At times turned sour and bitter this I say
Never think or claim love has diminished...
Not in wildest imaginations has wanned a bit
Such devotion I have of you, my dearest!

By fate we'll part ways; don't doubt my love!
Wherever I am won't lose memory of you,
It's an immortal love gotten my bones...
Either oblivion or death can't rip it out of me.

Need not to stay longer or live on earth together
Under any circumstances I bid goodbye today;
Weep not and hold on to my promise...
In heaven I wait to continue our love forever.
