ben seni
nefesin nefesime sığındığında sevdim

mürekkep siyahı akan kelimelerde sevdim seni
varlığında dahi yokluğunu düşünerek sevdim
aynası güneş olmuş gündüzler ile seviyordum seni
namlunun ucunda kör kurşunlara rağmen sevdim

my try 

I loved you when your breath took refuge in my breath.

I loved you in the words flowing  like inky black colour..

Although you were exist, I loved you by thinking your absence..

I loved you with the days in which the sun became mirror.

I loved you despite the stray bullets in the gun barrel..

Hi - can I have a question regarding this sentence?

aynası güneş olmuş gündüzler ile seviyordum seni

3rd person singular ending in word "aynası" suggests that sun became a mirror of something - is it "gündüzler" (sun became mirror of days/daytimes) or "güneş" (sun became mirror of itself)? Or perhaps both options are possible? Or maybe "-sı" refers it to word from one of preceding sentences? Or another answer ?

Yes, it is " gündüzler" that is referred. The sun as if became mirror of the days. The poet forced the limits of  his imagination bit far..

Everything´s clear now - thank you very much, Tunci, for your - as always, very valuable - help!
