Sure, Gray went through an emotional rollercoaster with the entire Silver stuff.

BUT, he should be smart enough not to blame Natsu for everything that he ever went through. As other have explained already.

It's not cuz it is what his father says, that it is true. If my dad would tell me the world is made of unicorn dung, there's no way I'd buy that.

Gray just needs to be smart and stand aside in order to let Natsu take care of Zeref. While Natsu, is doing that Gray should converse with the others about the new revelation or just start fighting the Alvarez soldiers.
