A source tells ET how Ben Affleck has been supporting his ex-wife since her father’s death and his future plans with Jennifer Lopez.

Ben Affleck is doing all he can to be supportive of his ex-wife, Jennifer Garner, as she mourns the death of her father.

A source tells ET that the 51-year-old actor and director has been “actively involved” with his 52-year-old former spouse as she grieves and “is supportive across the board.”

“He has been checking in on her and making sure she knows he is there for her since her dad’s passing. It was the kids’ grandfather and Ben and him always got along,” the source adds. “He considered him family and always will.”

Garner shared the news that her father, William Garner, “passed peacefully” at the age of 85 last month.

“We were with him, singing Amazing Grace as he left us (did we carry him across or scare him away— valid question),” she shared on Instagram, alongside a collage of family photos. “While there is no tragedy in the death of an 85 year old man who lived a healthy, wonderful life, I know grief is unavoidable, waiting around unexpected corners.”

However, Garner wrote, “Today is for gratitude.”

“We are grateful for Dad’s gentle demeanor and quiet strength,” she wrote. “For how he teased with a mischievous smile, and for the way he invented the role of all in, ever patient girl dad. We are grateful for his work ethic, leadership and faith.”
