Jennifer Garner said no when her boyfriend of almost five years, John Miller, asked her to move in with him.

Radar Online says that the star of “The Last Thing He Told Me” didn’t want her kids to have to adjust to another mixed family after they became close with their dad’s wife and her twins, Jennifer Lopez and Emme and Max Affleck.

Garner knows that it is already hard for Violet, Seraphina, and Samuel to split their time between two places, and if she moved in with Miller, she would have less time to spend with them.

“To invite another man into the house right now, one who has two teenaged children of his own, means her children would get even less time with her, and that’s just not an option,” the source said.

But the source said that doesn’t mean she’ll ever move in with him. “Jennifer loves John, and they see each other whenever they can,” the insider added.

Note that the CEO of CaliBurger has two children with his ex-wife, Caroline Campbell. Their names are Violet and Quest.

Us Weekly reported last year that after keeping their families separate for a long time, Garner’s kids have met Miller’s kids.
