Ben seni karşılıksız severken, ben senin için her şeyi yapabilecekken senin bundan haberin olmayacak ya, kahroluşlarım bu yüzden. Seni seviyorum; karşılık beklemeden,nedensizce seviyorum. Hiç vazgeçmemek üzere seviyorum. Sadece seviyorum,seviyorum. Sadece bunu bilmeni istiyorum.
While I love you unconditionally, while I would do anything for you, you won't acknowledge it. It is just because of this that I am sad. I love you, I love for no reason, without expecting anything. I love in order not to leave you. I just love you, love you. I just want you to know this.
Remarks about the translation
I don't like "I love in order not to quit you" this part of my translation. If it sounds natural to natives, no problem, if it is not , your comments will be welcomed..
What do you think about the suggestions below? Do they keep the meaning of the text?
While I love you unconditionally, while I would do anything for you, you won't acknowledge it. It is just because of this that I am sad. That's why I love you for no reason, without expecting anything. I love in order not to leave you. I just love you, love you. I just want you to know this.
No. 'without expecting everything' = I expect a lot, but there are some things I don't expect. 'without expecting anything' = there is nothing I expect in return. Looking at the context, it seems clear that is what is meant here.
