does anyone remember An Unmarried Woman?
It's from 1978, was nominated for a bunch of oscars. reminds me of this.
"Erica seems to have it all - a comfortable home, an interesting job in a Manhattan art galley, a bright teenage daughter, and a loving, successful husband. Then, suddenly, her life is shattered. Her "perfect" husband walks out, and she is left frightened and alone to face the chancy singles world. How does a vital, contemporary woman pick up the pieces and start over?"
"Go back to Jersey, sonny. This is the city of angels and you haven't got any wings."
