Shookus was also absent from Affleck's 46th birthday celebration before the date night with Playboy's Miss May 2018.
But it doesn't seem Affleck has fallen for Sexton, as a source told Us Weekly he seemed "somber" during the date.
"He sat outside with Shauna, and they got a lot of food," the insider said. "Ben arrived by himself and left by himself in his car. He tipped the valet with a $100 bill."
Affleck and Shookus were last photographed together on a trip to Puerto Rico in July. They went public with their relationship in July 2017.
Radar previously reported that the couple even had plans to tie the knot.
"They want to do it before end of summer when Lindsay goes back to work on SNL," an insider told Radar. "They love Hawaii and had a great time there in April when Ben was filming Triple Frontier."
Affleck and estranged wife Jennifer Garner split in 2015 after 10 years of marriage. They co-parent children Violet, 12, Seraphina, 9, and Samuel, 6.
