Ben Affleck On Co-Parenting 3 Children: ‘The Accountant’ Star Faces ‘Dilemmas’ Every Day

Ben Affleck is no stranger to challenges when it comes to parenting. The actor, who shares three children with estranged wife Jennifer Garner, revealed that his latest film, "The Accountant," made him realize a lot of important things about being a parent.

In the action thriller film "The Accountant," Affleck portrays Christian Wolff, a math expert who's also on the autism spectrum. Chris grew up under the military-esque guidance of his physical and strict father, who only wants what's best for his son but ended up abusing and brutalizing him.

Affleck, 44, said that the parenting style of Chris' father in the movie made him contemplate about his own, People reported. Affleck and Garner co-parent three children: 10-year-old Violet, 7-year-old Seraphina and 4-year-old Samuel.

According to Affleck, the parenting style of Chris' dad "was the most heartbreaking thing about the story" and it moved him as a parent. The "Batman vs. Superman: Dawn of Justice" star admitted that he is facing dilemmas every day "about what's the right way to raise children" and about "what's the right thing to teach them," adding that "every moment" has a "crossroad."

"When you have kids, what's that expression, 'Your heart is outside your body,' all of a sudden you feel so vulnerable and this fear of a child being vulnerable is very very powerful," Affleck shared, as quoted by People. The actor added that "The Accountant" (bowing in theaters on Oct. 14) offers a glimpse on what's the proper way to channel every parent's intense emotions for their child, and it isn't always a walk in the park.

Affleck and Garner make it a point to establish a solid familial foundation to their three kids despite their separation. It was reported last June that the family-of-five vacationed together in Europe while Affleck was in London, shooting "The Justice League: Part One," according to Us Weekly. In May, the family traveled to Paris and also spent time in Venice.

Affleck and Garner announced in June 2015 that they were divorcing after 10 years of marriage. The two, however, vowed to remain amicable for the sake of their children. Just last month, the pair was seen grabbing dinner together without their kids at The Hungry Cat in Santa Monica, California, a separate report from People revealed.

While promoting her film "Nine Lives" in August, Garner said that they are "definitely a modern family" and they are "doing really well." The 44-year-old actress said that her and Affleck's priority is their children and spending quality time with them is the most important thing of all.
