Can someone tell me if Charlie ever found out that he's daughter's boyfriend is a vampire and she chose to become a vampire too?

no but he supposes sth when he saw her with renesmee at cullen 's house.

no but jacob shows charlie that he is a werewolf so he knows something is up with bella

he didn't know at least from what i hear. my aunt told me all about the series so i read the 1st 3 বই and loved them. হাঃ হাঃ হাঃ :)

He never found out and the only way he would is if he saw her "hunting" for something to "drink".
