Jennifer Garner went to church with Ben Affleck and their kids on Sunday, amid reports that she's cooled things off with boyfriend John Miller.

Apparently, the actress feels she doesn't have enough time or energy to dedicate to a serious relationship with everything else she has going on.

"Jen has slowed things down with John Miller since the word got out they were dating. Jen’s children, career and Ben [Affleck] are her main focus at the moment and she is not ready for anything too serious. Privately, she has told friends she doesn’t want to be deeply committed at the moment. She wants to focus on family, career and getting Ben back on track. She enjoys her time with John but she has concerns of moving too quickly because she doesn’t want to be disappointed. Her friends are in full support of her stepping back a bit because they all know relationships take a lot of work and right now her plate is full," a source dished to ET.

"She still communicates with Ben almost daily because his sobriety is so important, she wants be a strong support and he leans on her a lot. She truly is a great friend to him and an amazing mother. Ben regrets so many of his actions in the past. He loves his family and knows his priority should have been them all along. The good news is that they work incredibly hard on keeping their family unit working for the children, despite the fact they are no longer married," the source added.

You've gotta hand it to Jen G for always having her priorities straight!
