An Unmarried Woman (1978)
Erica seems to have the perfect life: She is happily married, has a good relationship with her teenage daughter, a lovely home on the Upper East Side of New York and a fullfilling job at an art gallery. But when her seemingly happy husband leaves her for a younger woman, Erica falls apart. Gradually, as she adjusts to her situation, Erica begins to enjoy her new independence and when she falls in love with an artist, she has to choose between joining him for the summer or taking the well-paid position she has been offered and remaining on her own.
