Him's feed

Y'all keep on pushing that's she'll be human etc, like there's a possibility she's ghost until he dies or until the story ends. Her being a ghost doesn't hinder him having a relationship with her it's just going to seem like he's a loner and single on the outside.

It's entirely possible for them to be together as they are, no need for her to turn into human, if she does, it's a welcomed plotline, if she doesn't, then they can date as ghost and he can be loyal to only her for life
