Songfacts®:

• This song finds Alessia Cara asking a guy why he's stopped loving her.
  
  Won't ask you to stay
  But let me ask you one thing
  Oh, when did you fall out of love, out of love?
  Oh, when did you fall out of love with me?
  
  Cara wrote this song from the perspective of a friend of hers who was going through a breakup.
• This was the first song that Cara had ever written from someone else's standpoint. She explained in a video interview:
  
  "They were going through something and they were going through the end of a relationship where somebody has fallen out of love with them, and they aren't a songwriter and they didn't really know how to express this, so they came up to me personally and asked me, like 'hey, could you one day write a song about this - like about someone falling out of love with you?' I was like 'sure, yeah.'
  
  Cara kept her friend's request in the back of her mind and a few weeks later she was recording in the studio with the veteran producer Rick Nowels (Belinda Carlisle's "Heaven Is A Place On Earth," Dido's "White Flag"). She recalled:
  
  "I had no idea what to write about that day, and then that concept 'Out of Love' came into my head, and I sat down and wrote it in like 10 minutes. It was one of those things that came out so quickly - I have a recording of it actually, of us writing it; like he's playing on the piano following my melodies and my lyrics and the lyrics were falling out of me, and the chords are falling out of him, and it was like one of those weird cosmic things that just came together so quickly and naturally, and I was really freaked out at the end, I was like whoa, we really made something cool, and I had no idea what we were even making 10 seconds ago, and now we made this really awesome song."
• Cara played the song to her friend who got really emotional. She added that "they did get back together so I guess I'm just a really good wingman."
• The video features a montage of couples who are clearly on the verge of breaking up, with Alessia Cara on hand to witness the heartbreak. The singer explained on Twitter the clip's inspiration: "Because I didn't write this song about me I wanted the video to portray being a bystander to other people's stories," she wrote.
