On Gwen's reaction to his divorce: "I won't forget that day. I looked over at Gwen — who I didn't really know — and she had these huge tears in her eyes. I thought, 'Wow, she feels super bad for me!' . . . I thought it was going to be another one of those things-are-going-to-be-OK talks. She didn't tell me much, because we didn't know each other at the time, but she said, 'I'm going through something very similar to what you're going through. I understand. And I hate it.'"
On how the conversation started everything: "That's kind of how our friendship and bond started, that day. It went from that, to checking in on each other once a week through email — 'This sh*t happened to me, what happened to you?' — to maybe three times a week, then every day, to 'Hey, here's my phone number if you ever want to text.' Next thing I know, I wake up and she's all I care about, and I'm wondering if she feels the same about me."
On her "Used to Love You" song: "Right when she wrote the song, she was like, 'My gosh, I put exactly what I wanted to say into a song.' Sometimes it's hard to put it exactly how you want to say it when it's that personal to you, and so she was so excited that she got that out, and then it ends up being this smash song that it's turning into."
On how Gwen saved his life: "Gwen saved my life. Who else on earth could understand going through a high-profile divorce from another musician? You can't even imagine the similarities in our divorces."
