The duo, who began dating in 2011 after meeting on the set of the movie, 'The Place Beyond the Pines' and have always been notoriously private about their romance, ended their relationship over Christmas because they wanted different things.
A source told InTouch magazine that the 39-year-old actress and the 33-year-old 'The Notebook' star are still on good terms.
The insider said: ''They started having problems back in September. They decided to quietly call it off for good around Christmas. There is no ill will.''
The heartthrob has retreated to his native Canada to get over their break-up.
A friend told Life & Style magazine: ''Neither is rushing out to date other people right now. They just knew it was time.
''They knew it was time to take the next step and get married. But neither was sure they wanted that to happen.
''He packed up and moved back to Canada for a while. He felt like he needed time out of the limelight to refocus.''
Ryan's desire to start a family and Eva's love of the spotlight drove the couple apart.
A source explained: ''Eva loves Hollywood, the parties, the glamour, loves going out,'' and added Ryan is ''introverted, very serious and a total homebody.''
The 'Training Day' actress previously admitted she wasn't interested in becoming a mother.
She said: ''I'm certainly not thinking about being a mom. I can't imagine it. I'm too selfish.''
While Ryan said in the past he would love to be ''making babies.''
A spokesperson for the brunette beauty declined to comment.
