Inside Ben Affleck and Lindsay Shookus’ Rekindled Romance: 'He Loves to Be With Her'

They’re officially back together, and according to pals, things are going great between Ben Affleck, 46, and Saturday Night Live producer Lindsay Shookus, 38.

“He and Lindsay are spending time together. He loves to be with her,” an Affleck source tells PEOPLE, adding that “they still are both focusing on their families.” (Affleck shares daughters Violet, 13, and Seraphina, 10, and son Sam, 7, with his ex-wife Jennifer Garner; Shookus shares a young daughter with her ex-husband Kevin Miller.)

“She has been a positive impact on his life,” a Shookus insider adds. “They had remained friends, and started their relationship again. They’re obviously back together. She is his number one supporter.”

Of course, Affleck also has Garner in his corner: Discussing his ongoing struggles with alcoholism In a March 4 interview with Today, he said, “When somebody’s the mother of your kids, they’re going to be the most important, central person in your life and that’s good.”

Affleck and Shookus first split up last August after a year of dating, shortly before Affleck was seen on a date with Playboy model Shauna Sexton. He soon went back to rehab to treat his alcohol addiction. An Affleck source said at the time that his breakup with Shookus was “amicable but unfortunately it didn’t work out, partly because of work obligations on different coasts….they truly cared for each other and tried to make it work.”

Now they’re definitely back on track.

“Ben and Lindsay have picked back up where they left off at this point,” the Shookus insider says, adding, “They have a wonderful, caring relationship and a healthy lifestyle together.”

Shookus was seen supporting Affleck at his March 3 premiere party for his new Netflix action movie Triple Frontier, where the duo stayed close all night at the afterparty. The movie, which also stars Charlie Hunnam and Oscar Isaac, hits theaters March 6 and Netflix March 15.

Affleck and Shookus were also recently spotted in Los Angeles together dining out at Katsuya restaurant and getting coffee together the next morning.

The Affleck source adds that the Oscar winner has been in a really good place recently with his career and sobriety. The source says, “Life has its challenges, but Ben has been doing great.”
