Hmmmm... a title... *scratches head*. I'll keep thinkin' for ya, Smalls.
I like where you're going with this. There are a couple of places that throw me off a bit, but, as usual, it's just personal preference. Which means that you're free to ignore me, lol.
The first line. 'The dark night'... I might change that for something that indicates the feel of the night in question instead of its appearance, since all nights are dark and it doesn't give it the same feeling as the rest of your poem... something like
When I first saw you
the night sky crept in
devouring light's last trace
foreshadowing
things to come.
I've got a screaming headache, so bear with me if that's not quite right, but maybe it'll help regardless.
The only other thing was 'heartbroken'. I think 'aching' works better there, mostly just because 'heartbroken' seems to be a bit of a leap from the rest of your lines, whereas aching seems to fit perfectly. Or even ravaged or despondent or... you pick

.
That's my two cents. I enjoyed your work, like always, and think that I'll come back and read it again when my head isn't splitting in two.
Still trying to think of a title for you...
