What went wrong?
It's hard enough to be in a marriage, and then have a kid, then kids, it changes everything. For me, I'd become more concerned with my children. Not that I ignored Britney, but my kids are always most important ... I mean, we were having complications. I didn't give her an ultimatum, but I was trying to work stuff out with her, and she didn't even talk to me or anything and went behind my back and filed [for divorce]. [I was] completely blindsided.

A lot of people assumed you fought for custody of the kids because of money.
My first question to [my lawyer] was, "Am I ever going to be able to see my children?" I told him that I would spend every last dime that I had to make sure that my children are okay. That's all that mattered. I didn't know how much power Britney had. That really scared me.

What are your happiest memories of the marriage?
Well, getting married. I never thought that I would get married but it wound up happening. That was a really, really, happy, exciting moment. I pretty much realized that I was giving my life to her, and I was doing it without question.

How did you react in January when Britney locked herself in the bathroom with Jayden and was later taken to the hospital on a gurney?
That whole night is a blur. You want to talk about one of my lowest points of depression, that was probably one of them. I was very, very worried for her 'cause I care about her. That's the mother of my children. Just because I'm not in love with her doesn't mean that I don't love her. I'm definitely rooting for her. There's nothing more that I want than for her to be in the best health and doing what she loves to do.
