Ben Affleck and Jennifer Garner continue to keep things cordial while having a friendly dinner on Sunday in Malibu, California.

The exes, who announced their divorce in June, have been carving out quality time to be together with their three children, Violet, 9, Seraphina, 6, and Samuel 3, since returning home to Los Angeles after spending the summer in Atlanta. However, it appears the kids were left at home while Affleck and Garner hit up at a popular sushi restaurant this past weekend.

The group dined for nearly three hours with family, and Affleck and Garner were friendly throughout the night, with Affleck even holding the door open for Garner, reports Entertainment Tonight.

The two have made it clear that despite their pending divorce, they still care deeply for one another.

“They are working together and are keeping it amicable,” a source close to the couple also tells PEOPLE. “This is something they have been working on for over a year – and they continue to be strong unit.”

A second source also says they’re choosing to remain friendly for reasons that extend beyond parenting.

“It’s not just for the kids – it’s also for them” says the source. “They care about each other.”

Affleck and Garner have been spotted spending weekends taking their kids to the local famers’ market and attending church services as a family.

And as the family continues to step out as a unit, observers have noticed that Affleck and Garner seem to be looking happier after a tumultuous summer.

“His family is all [Ben] cares about. This is what makes him happy and it makes sense that he looks happier,” a source tells PEOPLE. “He enjoys the time with his family and that includes Jen.”

The divorce, meanwhile, is moving forward as planned, a family source tells PEOPLE, and neither Affleck nor Garner “seem rushed” when it comes to hashing out the details.

“[Jen] can’t even imagine dating,” the source adds, noting that “it will probably be a long time before she is able to move on romantically.”
