So what else is happening for Cristina in the upcoming episodes? Here's an update from other sources:
Cristina and Owen: Letting go will be hard to do
“Now there’s a resigned acceptance of the fact that they want different things,” says Oh. “[The next few episodes will] grow them through that in a mature way — even though they’re still hooking up.” But will Owen ever make a move to finding a life outside of Cristina? McKidd thinks that could be in the cards. “She keeps pushing him to move on, so I think he’s going to try to move on." - Entertainment Weekly
Sandra Oh: "You'll see how certain things change and certain consequences for Cristina. In the 200th episode, she gets a glimpse of the impact of her decision (telling Owen they should date other people). She'll get a glimpse of what it is and have to continue holding fast to that decision and being supportive of each other." - THR
