In an interview in GQ magazine, on newsstands Friday, Pitt expresses nostalgia and happiness for his 4 1/2 years of marriage with Aniston, who filed for divorce in March.
"There's a beauty in our coming together, there's a beauty in our time together, and there's a beauty in this, for us," Pitt says. "I'm actually really proud of us. ... We've done it our way, and I love her for that. We've kept the love we have for each other."
On reports that he wanted children, but Aniston didn't, Pitt says: "That was one version," but totally unfounded.
As to reports of a romance with his "Mr. and Mrs. Smith" co-star Angelina Jolie, Pitt didn't explicitly deny them, but said he pays it no mind.
"Jen and I have felt pretty impervious to it all. We have not seen a thing, so that we can carry on this new incarnation with the love we still have for each other. My attitude was, say what you want, we're not playing."
Instead, Pitt describes the reasons for their breakup as "complex and multifaceted" and "not one thing."
"Anything worth anything is a beast. The thing I don't understand is looking at this as a failure. It's talked about like it failed, I guess because it wasn't flawless," Pitt said. "Me, I embrace the messiness of life. I find it so beautiful, actually."
Now, the 41-year-old actor says, he has growing interest in doing things other than movies: "I've got a few years left of a good run. And truthfully, I'm interested in other things now. Like family."
Though Pitt says he's not ready to remarry and start that family yet, he adds: "I'm not worried that it's not gonna happen. I'll make it happen. You go make the thing that you want."
But would he marry someone who isn't a celebrity? He's not willing to go that far.
"No, because I like so much the people I've spent time with," Pitt said. "I've had great experiences, great schooling, great laughs."
