Splendor (1999) on Netflix

An average, calm mid-20s girl named Veronica restarts her dead dating life all of the sudden, but with two guys: a sensitive failed writer named Abel and an airheaded drummer named Zed. At first she despairs. Then she finds a way to date both without their finding out. Then she tells both about it. Then Abel and Zed meet each other, and, after much initial conflict, they wind up living together and evolve into a very odd yet happy threesome. However, as time goes by Veronica starts growing apart from them, while Abel and Zed become brother-like (and kid-like). So when a director starts courting a pregnant Veronica, strains ensue. Will Abel and Zed be able to grow up and save the day?...
