"I believe in the sanctity of marriage. John and I, you know, we were both in long marriages and it's not something that we need to rush back into," the double Oscar winner, 36, tells September's InStyle, on newsstands Friday, about her agent-beau of nearly four years.
The same goes for starting a family together. Already a mom-figure in Campisi's son's life, Swank says that although she's thought about having kids "since a really young age," she'll wait until "the time is right."
Even though the Oscar winner may have gone through a painful breakup with Chad Lowe, she only sees the positives in their split.
"A lot of people look at divorce as a failure. I really look at my relationship with Chad as 14 years of success," she says about her ex, with whom she separated in January 2006. "I will carry him in my heart forever. He's a part of me."
"Friends of mine and I talk about this. Does someone come into your life for a certain time, and then you are supposed to go your separate ways?" she asks. "There's a part of me that thinks that's true."
There are friendships, Swank says, "that we grow out of. But I believe in the long haul. I believe in having a monogamous relationship."
