Sometimes I worry about our future. For you it seems quite easy, but you have to understand I am a lot older than you. You are happy to not think about the future, but I need to know we have a future together, because if we don´t, I don´t think we can be together. I´m too old to play around. I need to know I am not wasting my time with you.

Sometimes I worry about our future.

Bazen geleceğimiz hakkında endişeleniyorum.

For you it seems quite easy,

Senin için çok kolay gözüküyor,

but you have to understand I am a lot older than you

ama senden çok yaşlıyım bunu anlamak zorundasın.

You are happy to not think about the future,

Gelecek hakkında düşünmemek seni mutlu ediyor,

but I need to know we have a future together

ama bizim geleceğimizin olup olmadığını bilmem lazım

because if we don´t,

çünkü eğer yoksa

I don´t think we can be together.

beraber olabileceğimizi sanmıyorum.

I´m too old to play around

Boş yere oyalanmak için çok yaşlıyım.

I need to know I am not wasting my time with you.

Seninle vaktimi boşa harcayıp harcamadığımı bilmeye ihtiyacım var.

Dear Tunci could you explain why you used bilmem lazım and then bilmeye ihtiyacım var please

Actually there is no difference. Both means same. He might have used it to have a diversity.

Thanks Tunci. Much appreciated

 Birşey değil Joa.

 Deli, Faruk is right. Both means same. I  just wanted to use them to have a diversity in the translation.
