Billy Bob Thornton has been married and divorced five times — the last time to Angelina Jolie from 2000 to their split in 2002.

Billy Bob has a new memoir coming out, The Billy Bob Tapes: A Cave Full of Ghosts, and Angie — who is 20 years younger than her ex — wrote the introduction. Billy Bob talked to ABC’s Nightline about their relationship, taking full responsibility for the marriage's demise.

“I blew it because I didn’t think I was good enough for her,” he told ABC (via RadarOnline). “She has one way she wanted to live her life and I had another way to live mine. I was just too insecure. ... We had a great marriage and I chickened out because I didn't feel good enough. That's all that happened. It was no big deal, we never hated each other."

Now Angie is engaged to Brad Pitt, who probably doesn't have so many insecurities about being good enough for her. But we're just guessing on that one.

Watch Billy Bob talk about his "eating disorder" (he went overboard losing weight for a role, ending up 6-feet-tall and 128 lbs.!) and other eccentricities here in this video clip.
