Brad Pitt is becoming more at peace with his newfound single life, but he’s in no rush to enter the dating world.

Recently, Pitt has been “in better spirits” since weathering a difficult split from Angelina Jolie in September after 12 years together. As the two work with a private judge to resolve the divorce and custody, “things are definitely calming down,” an insider tells PEOPLE in this week’s issue.

But moving on with his love life isn’t a priority, sources say. Instead, the actor, 53, has been enjoying a low-key social life and reconnecting with pals.

“He often has friends over,” says the insider. “Old friends are back in his life, and he seems happy about it.”

And the two-time Sexiest Man Alive has been working out almost daily. “He’s lost a few pounds,” says a second source. “He’s in very good shape.”

Along with spending more time with his kids, Pitt has been dabbling in a new hobby — sculpture — while also keeping busy with work, lining up his next movies as an actor and a producer.

“He seems much happier,” says the second source.
