In the recent season premiere, Cristina (Sandra Oh) decided to have an abortion and Owen (Kevin McKidd) went with her although he disagreed with her choice.
Rhimes has now told TV Guide that the couple still care for each other despite their recent arguments.
"The love is still there," she said. "I didn't want to create situations this season where something happened and they broke up. What's adult about this is to give our characters impossible situations and see how they make their way through it together."
However, Rhimes confirmed that Cristina and Owen will still face problems in their relationship.
"They were in an impossible position where he wanted one thing and she wanted another, and he gave her what he felt she needed," she said. "It's going to put them in a strange position with one another for a while."
Grey's Anatomy airs on Thursdays at 9/8c on ABC.
