An Unmarried Woman (1978)

Erica becomes an unmarried woman, temporarily, after her successful, wealthy husband of 16 years leaves her for a girl he met while buying a shirt in Bloomingdale's. This movie shows Erica coming to terms with the break-up while revising her opinions of herself, redefining that self in its own right rather than as an extension of somebody else's personality, and finally going out with another man. Erica refuses to drop everything for Saul, an abstract expressionist painter, simply out of love for him, because he expects this of her. Loneliness is not her problem; but problems are brought to her new sense of independence by men that start flitting around this newly "available" woman like moths round a flame.
