To my understanding the above phrase is the answer to a question. It means that the answer will be "NO" and will NEVER change in the whole lifetime.
However, I may be wrong.
Hi Ilona, you got the meaning of it but the italian is wrong, the correct phrase would be "E' e sarà per sempre NO" or "E' e sarà per tutta la vita NO"
i was trying to help Inulek, not arguing on your translation
I'll edit that, so you can eventually fix your translation.
