It’s been about ten years since Billy Bob Thornton and Angelina Jolie have been together, and now the actor is opening up about his feelings about the celebrity mother-of-six. Billy Bob says he always felt like he “wasn’t good enough” for Angie and that the two actually did have a good marriage.

He tells Nightline:

“I blew it because I didn’t think I was good enough for her. She has one way she wanted to live her life and I had another way to live mine and I was just too insecure.

When you’re in a relationship, any two celebrities or whatever, you know, I think that puts on a lot of pressure. When Angie and I got married, during that time, I was more famous than she was to start with and then when she becomes this big thing, it’s hard in these relationships. I did feel like the Phantom of the Opera hiding in the catacombs. People have actually said that I didn’t deserve to be with her. 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.”

I guess we’ll never find out the true reason why the two broke up (although there were rumors that he wasn’t crazy about Angelina adopting Maddox back then), but could you imagine Billy Bob and Angie having six kids together? Brad Pitt just seems like a better fit for her, especially since they have the same views on family values.
