Can you help me find the name of this movie?

I’m trying to find the name of a movie that I saw while on a cruise with my best friend that actually helped me decide to give my husband a second chance. It had to have come out by or before 1999. I believe it was a French movie and in it the main character decides to give her ex-boyfriend a second chance. Do you have any suggestions or ideas? I thought the title was something like twice upon a lifetime, but I haven’t been to find that.
