"Don't Wanna Break Up Again" blends '90s R&B and pop influences, with Ariana Grande's vocals conveying a mix of indifference, exhaustion, and a lingering desire. This song, Track 3 on her Eternal Sunshine album, explores the complexities of a strained relationship.

Grande sings of her emotional pain while simultaneously grappling with the pull to stay connected. She acknowledges an unbalanced dynamic ("this situationship has to end") where efforts to improve ("spent so much on therapy") feel unmatched. Despite the strong urge to avoid another painful separation ("I don't wanna break up again"), a deeper understanding emerges. The song recognizes that ending the relationship, however difficult, might be necessary to prevent further emotional harm for both parties.

Speaking to Zach Sang for Amazon Music, Grande described "Don't Wanna Break Up Again" as the "hangover" of "Bye," suggesting a lingering effect from the previous song's themes. Both songs deal with the aftermath of a relationship, but "Don't Wanna Break Up Again" focuses more on introspection and processing the situation. Grande said: "There are so many polarizing feelings that we experience as human beings with regards to one's situation, and that's what I like about these two being back to back, because in "'bye' I say, 'at least we know we tried, didn't we? The two of us, we did good,' and then in 'Don't Wanna Break Up Again' it's like, 'you didn't even try 'til the end.' Both feelings exist at different, and I like the humaness of that. I like that they are layered and complicated, and all of the different emotions that come with loving and leaving, are kinda showcased, I guess."
