Who Did Raj Almost Marry?

Later in Season 12, the couple's relationship hits a serious snag when Raj sees Anu in what he thinks is a compromising situation. In Episode 11, "The Paintball Scattering," Raj helps Anu set up a doorbell camera only to see her ex-boyfriend arrive and go inside. The two argue, with Anu angrily telling Raj that nothing happened and that her ex was just picking up a few things — and though Raj tries to win her back in the following episode, "The Propagation Proposition," they agree that getting married might not actually be the best idea.

They start dating without being engaged, but trouble strikes yet again when Anu is offered an exciting job in hotel management while traveling for work in London. Raj wants to fly out and join her, but his best friend Howard Wolowitz (Simon Helberg) convinces him not to, saying that Raj should stay home with his friends and try to find a new girlfriend whose life trajectory aligns more closely with his. Raj and Anu split for good when she moves to London.
