Ryan Dorsey "can't watch" old footage of Naya Rivera performing

He told People: "[Josey] sat there and he watched the whole movie, and you could see his eyes welling up a little bit.

"But he's a strong boy, and he has a lot of content and episodes. His mom will live forever. I think that's a silver lining of this terrible situation. Pictures are hard enough. I can't just sit there and watch her sing. It's hard for me."

Ryan explained that he is reminded of his wife - who had managed to user her son to safety before she died - when he hears certain songs and struggles with the relation of "what could've been" had the tragedy not occurred.

He said: "So many songs make me think about her, like Amy Winehouse's 'Valerie,' which she sang on Glee, and 'Sunflower' by [Post Malone and Swae Lee] because I always used to get her sunflowers on Sundays.

"I can just see Josey in the back seat bobbing his head and singing that song.

"Sometimes they're happy reminders but a lot of times, even if it's happy, the reality is it's a lot of what could've been, what should've been.

"A lot of second-guessing everything and wondering how things might've played out if the tiniest decision we make really changes the course of events of life."
