Olivia Munn and Joel Kinnaman Split
04/30/2014 AT 02:30 PM EDT
The Newsroom actress, 33, and The Killing actor, 34, "are not together," a source tells PEOPLE.
"There have been a lot of travel changes in their relationship – their time together has been limited. They used to do everything together," the source adds.
The relationship had been serious enough for Munn to travel to Sweden, where Kinnaman grew up, and to meet his parents.
Kinnaman recently starred in the remake of RoboCop, and Munn told Allure in its May 2014 issue, "If there was ever going to be a girl who would want her man to bring home a RoboCop suit, it would be me. Joel is truly fantastic in it."
Munn previously dated Star Trek star Chris Pine.
