The notoriously private couple has been dating since 2011.
"It’s just really funny in the moments when we’re playing these absolutely absurd things," Van Camp mused. "For almost three years now, I’ve been playing with these heightened emotions —- someone who’s so much more tortured than I could ever be, with so much more anger than I could ever have.
"I call him ‘wife-beater Daniel.’ It’s hard for my family to watch. At a certain point, it does start to weigh on you physically and mentally, and suddenly you’re not coping with things as well.
