The 43-year-old actress, who announced her split from Ben Affleck in June after 10 years of marriage, is feeling "more relaxed lately" but isn't ready to find love again.

A source close to the 'Dallas Buyers Club' star said: "It will be a long time before she even cares to focus on dating."

The brunette beauty is eager to spend as much time with her children, Violet, nine, Seraphina, six, and three-year-old Samuel, when she's not working.

The insider added: "[She's] focusing on what makes her happy."

Meanwhile, the actress and Oscar winner Ben, 43, are planning to celebrate Thanksgiving and Christmas together, but don't want people to think they are rekindling their relationship.

The source told PEOPLE: "They are trying to figure out how they can best spend them together."

Ben is currently shooting in the upcoming film 'Live By Night' in Boston, but has been making regular trips back to Los Angeles to see their children.

The source said: "[He] has spent every possible hour of the day working. He's the first to arrive and the last to leave."
