Garner went on to admit Affleck would always remain "the love of my life", and insisted she had no regrets about tying the knot with her Daredevil movie co-star, lamenting, "he's just a complicated guy."

Now Ben has shared his thoughts on Garner's interview with the New York Times, revealing he was given a heads-up about its release.
He also admitted he can understand why Garner wanted to clear everything up in one big chat.
"She felt like she wanted to discuss it and get it out there and get it over with," he explained. "So she could say, 'Look, I already talked about it - I don't want to do it again."'
However, that doesn't mean Affleck is comfortable discussing his high-profile marriage breakdown - he resisted addressing it in public "for the sake of his three children", according to the Times.
He did insist, however, that they're still working as a team to raise their kids.
"Jen's great. She's a great person," the 43-year-old stated. "We're on great terms. I just saw her this morning, so that's the reality that I live in."
The estranged couple is reportedly still living together, with Affleck occupying a guest house on the grounds of the stars' marital home, so he can stay close to their children, Violet, 10, Seraphina, seven, and Samuel, four.
