The Love Wager by Lynn Painter

Hallie Piper is turning over a new leaf. After belly-crawling out of a hotel room (hello, rock bottom), she decides it’s time to become a full-on adult.

She gets a new apartment, a new haircut, and a new wardrobe, but when she logs into the dating app that she has determined will find her new love, she sees none other than Jack, the guy whose room she’d snuck out of.

Through the app, and after the joint agreement that they are absolutely not interested in each other, Jack and Hallie become partners in their respective searches for The One. They text each other about their dates, often scheduling them at the same restaurant so that if things don’t go well, the two of them can get tacos afterward.

Spoiler: they get a lot of tacos together.
