Grande dated Mac Miller from 2016 to early 2018, and while their relationship had some adorable moments, she also noted that it was "toxic" at times due to his issues with sobriety. "Better Off" is an iconic breakup anthem about their split. It's not the only time Miller has been referenced in her music: her new track "Thank U, Next" has a decidedly sweeter take on their relationship, with her commenting she wishes she could "say thank you" to him.
