ترجمه - پرتغالی برزیل-انگلیسی - eterno futuro marido, eu te amo.

I'm not sure whether "Eternal" could translate the Portuguese word "Eterno" here. "Eterno futuro marido" means something like "one who is to be a husband in the future, but doesn't want/cannot marry, so he remains a 'future husband' indefinitely".
