Ok, so it started off with this guy and girl who meet while waiting in line somewhere. The movie follows their relationship and all the problems they have. I remember this one scene when they’re in Paris and the woman asks “do you ever dream of me?” Or something like that. They eventually break up and the girl goes off to marry some other guy. They reunite though and I guess the guy had a realization that their love was “written in the stars” or something similar. It somes really corny but it’s actually pretty realistic. I can’t remember the year but it’s not that old.
“Serendipity”(2001) ?
