The Do Over by Lynn Painter

After living through a dumpster fire of a Valentine’s Day, Emilie Hornby escapes to her grandmother’s house for some comfort and a consolation pint of Ben & Jerry’s. She passes out on the couch, but when she wakes up, she’s back home in her own bed—and it’s Valentine’s Day all over again. And the next day? Another horrendous V-Day.

Emilie is stuck in some sort of time loop nightmare that she can’t wake up from as she re-watches her boyfriend, Josh, cheat on her day after day. In addition to Josh’s recurring infidelity, Emilie can’t get away from the enigmatic Nick, who she keeps running into—sometimes literally—in unfortunate ways.
