Mango - La rondine. translation pls...?

Hi! Could someone translate this gorgeous song..? Grazie tanto!

Ti vorrei, ti vorrei, come sempre ti vorrei
notte farà, mi penserai
ma tu che ne sai dei sogni
quelli son miei non li vendo

Che ne sai, che ne sai, chissà che mi scriverai
forse un addio o forse no
ma tu che ne sai dei sogni
...

nonostante tu sia la mia rondine andata via
sei il mio volo a metà
sei il mio passo nel vuoto

dove sei dove sei
dove sei dove sei dove sei
unico amore che rivivrei.

sai di vento del nord
sai di buono ma non di noi
stessa luna a metà
sei nel cielo sbagliato.

Non lo so, non lo so
quanto tempo ammazzerò
mio libro mio
non ti leggerò

baciandoti sulla bocca
lo scriverò un'altra volta.

nonostante tu sia la mia rondine andata via
sei il mio volo a metà
sei il mio passo nel vuoto

dove sei dove sei
dove sei dove sei dove sei
unico amore che rivivrei.

sai di vento del nord
sai di buono ma non di noi
stessa luna a metà
sei nel cielo sbagliato.

nonostante tu sia la mia rondine andata via
stessa luna a metà
sei nel cielo sbagliato.

I want you, I want you, like always, I want you
it’ll be night soon, will you think of me?
but what do you know about dreams?
those ones are mine, I don’t sell them

What do you know, what do you know, maybe you’ll write to me
maybe a good-bye, or maybe not
but what do you know about dreams?

Even if you are my gone-away swallow
you’re still my halfway flight
you’re a step into the vacuum

Where are you, where are you?
where are you, where are you, where are you?
My only love which will revive

you know about the winds from the north
you know of goodness, but not of us
the same halfway moon
you’re in the wrong sky

I don’t know, I don’t know
how much time I’ll kill
my book, mine
I won’t read for you

I’ll re-write it once again
while I kiss you on the lips

Even if you are my gone-away swallow
you’re still my halfway flight
you’re a step into the vacuum

Where are you, where are you?
where are you, where are you, where are you?
My only love which will revive

you know about the winds from the north
you know of goodness, but not of us
the same halfway moon
you’re in the wrong sky

Even if you are my gone-away swallow
the same halfway moon
you’re in the wrong sky

Citlalli's translation seems OK, but necessarily literal. Here's my translation, which is a bit more poetic, and which tries to capture the spirit of the lines. The two biggest problems were doing something with the half moon image, which has no particular poetic meaning in English, and also the concept of "the wrong sky." The implication is that because you've gone there's something wrong with the moon and/or the night sky. The problem is to render that poetically, not literally. The third problem is the vacuum or void, neither of which is especially evocative in English. I thought about going for "emptiness," and decided to just shoot for the idea of "alone."

The Swallow

I want you, I want you
Like I've always wanted you
The night comes; will you think of me?
What do you know about my dreams?
They’re not for sale, they belong to me

This you know, this you know
Only heaven knows what you’ll write to me
Maybe goodbye, maybe hello
What do you know what’s in my dreams

Now like the swallow, fly away
You’ve flown away with half of me
Left me here, all alone

Where are you, where are you
Where are you, where are you, where are you
Only with your love can I live again

You know how the north winds blow
You know so much, but not about us
Without you, only half the moon
Runs across
My night sky

I don’t know, I don’t know
How much time I can wile away
Rewriting the story of my life
And how I want to kiss your lips
I’ll try to write another day

Now like the swallow, fly away
You’ve flown away with half of me
Left me here, all alone

Where are you, where are you
Where are you, where are you, where are you
Only with your love can I live again

You know how the north winds blow
You know so much, but not about us
Without you, only half the moon
Runs across
My night sky

Now like the swallow, fly away
Like the swallow, fly away
Without you, only half the moon
Runs across
My night sky
