"They have very different personalities and weren't on the same page when it came to their future," the source tells PEOPLE.
According to the source, the Fargo actress, 33, and Hedlund, 31, had been experiencing relationship problems in the months leading to the split.
"Their relationship has been very rocky for a while, so the breakup is actually a relief for them."
The former couple met on the set of On the Road in 2010. Earlier this year, the two were noticeably together at the Golden Globes and also attended Fox's award show party.
