Get gone, girl! Jennifer Garner knows that her estranged husband, Ben Affleck, is getting more serious with his new girlfriend, Lindsay Shookus. However, an insider tells In Touch that the 45-year-old actress is adamant that her ex’s ladylove never meets the former couple’s three children, Violet, 11, Seraphina, 8, and Samuel, 5.

“Ben really wants to introduce Lindsay to his kids, but Jen has put her foot down,” says the source, explaining that the Alias alum, who, with Ben, 45, announced their split in 2015 after 10 years of marriage, thinks it’s too soon for the kids to meet the Saturday Night Live producer, 37. “It’s taken the whole family a long time to adjust to the divorce. Bringing Lindsay into the picture could be very jarring.”

While he would like to introduce Lindsay to the kids, Ben understands where Jen is coming from. “They are both extremely dedicated to making this a seamless transition for the kids,” says a Ben insider, but the Gone Girl actor also thinks his relationship with Lindsay is solid.

“They’ve barely spent any time apart [sine going public in July] and have even talked about marriage,” the source says. Ben is keeping his fingers crossed that Jen will eventually change her mind. But he knows that it might take some time. “Jen’s in denial about how serious Ben and Lindsay are,” says the source. “She also doesn’t want Lindsay to play stepmom to her kids.”

Whether Lindsay — who is already mom to a four-year-old daughter with her producer ex-husband, Kevin Miller —ever gets to meet Ben’s young’uns, she and the Oscar winner are already considering having kids of their own. “They’re actively talking about having a baby,” an insider previously told In Touch. “They’re ready to start a family.”
