Life Lessons (1989)

Lionel Dobie is an acclaimed abstract artist who finds himself unable to paint during the days before a scheduled gallery exhibition of his new work. Paulette is Lionel's assistant and former lover. Lionel is still infatuated with her, but Paulette wants only his tutelage, which makes things difficult since they live in the same studio-loft. Paulette dates other people, including a performance artist and a painter.
