The 52-year-old actor is also hoping to see the six children he shares with Jolie soon, the source adds. Jolie and the kids are currently living in a rental in Malibu, California, where they've been since news of Jolie and Pitt's split broke last Tuesday.
According to the source, a difference of priorities is one reason for the A-list couple's surprising breakup after two years of marriage, saying that Jolie, 41, has increasingly moved away from Hollywood to focus on her activities as UNHCR Special Envoy, while Pitt is still very much interested in making films.
"Every marriage has priorities and they have been able to navigate them up until now," the source says. "Brad has different priorities. He's a leading actor with movies coming out. She has her things she wants to do and no one is saying that’s wrong."
However, Jolie's globetrotting activities are apparently a point of tension between the pair.
"Her global ambitions are part of the current problem -- I don't think anyone wants their kids all over the place," the source adds.
Last week, our source said that despite Pitt being taken by surprise by Jolie's divorce filing, Pitt refuses to badmouth the Maleficent actress.
"He will only say positive things about [the] mother [of his children]," the source said. "He has also made it clear to friends to not say anything negative about her. He continues to hope that there is an amicable resolution in the interest of the kids."
As for the alleged incident that happened on a family flight home from France earlier this month that reportedly prompted Jolie to file for divorce, our source says it was actually a "normal" tiff between Pitt and their 15-year-old son, Maddox.
"There was no inappropriate physical contact. Nothing inappropriate happened," the source said, noting that this was “totally a child-parent disagreement" and that any reports of inappropriate physical conduct are "exaggerated or untrue."
Jolie has asked for physical custody of their children in her divorce filing, which in addition to Maddox includes 10-year-old Shiloh, 12-year-old Pax, 11-year-old Zahara, and 8-year-old twins Vivienne and Knox. Our source tells ET, however, that Pitt wants to be with his kids and have some custody.
"Brad has traditional parenting skills -- thinks the kids need structure [like] bed times, consistent schooling," the source said. "Angelina's parenting style is much more freeform. She's not into setting boundaries."
