Dusk Maiden of Amnesia: A Ghost Girlfriend?

I'd be willing to call a ghost my girlfriend but to tell your friends about that seems like you'd be asking them to ridicule you. You'd have to get through the whole "ghosts aren't real" discussion and somehow prove it, it seems like to much work.

So yes I'd consider it [esp since she looks the same even after 60 years of being a ghost, actually if she is like Yuuko no objections regardless] but no I wouldn't inform my friends about her unless they can somehow see her themselves.
