Sorry, my English isn’t perfect.
Film ~ 2010 – 2016
About the movie: A girl at university gets dumped by her boyfriend, she studies physics and finds a way to move into alternate branches of probability (parallel universes using a spinner) to find one where they are happy, but realizes there is no such universe and goes back to live on
Been looking for this movie for years…it’s in English!
Happy Death Day 2U (2019)?

Thank U, but no, I watched the movie in 2016. The girl could live not one day, but many years in another world)
