"The Four Seasons," 1981, Alan Alda's directorial debut. Three couples vacation together over the years; one husband has a mlc, dumps his wife, assumes he'll remain part of the group....
I remember that film. Very well done. If I recall, in the beginning, the group feels quite bad about their friend dumping his wife and taking up with a woman about half his age. But in the end, they accepted him and the OW and everyone lived happily ever after.
