Accidentally on Purpose Episode 1.07 The Godfather

When Billie asks Abby and Nick to be the baby's Godparents, their strange response indicates a problem, which turns out to be that Abby wants to start a family and Nick is non-committal. Billie urges Abby to push Nick for an answer, which backfires, and Abby moves out. Billie figures that once Abby lets off a little steam she'll go back home and work things out. But a fun night on the town goes awry and Billie must stop Abby before she does something that will destroy her marriage. In a parallel story, Billie meets a nice new guy who asks her out. Zack questions the motives of a man who would asks out such an extremely pregnant woman. She's offended that Zack thinks only "pregnophiles" would find her attractive, but becomes more and more suspicious during her date.
