A movie made after 1990. The only thing I can remember is that this is the story of a couple who, at some point of the story, buy an object at a flea market or so. Then they break out, get back together and go to the flea market again. In my memory it might be raining the second time, but I am not sure of that. Until recently I thought it was "the eternal sunshine of the spotless mind" so there must be some similitude.
I know this is very vague but I really have nothing else.
