"Not only am I a lot of the guys in the book, but I am also a lot of the girls in the book," Greg says. "I've been there. I've been with someone who didn't like me, cheated on me, treated me badly. I still had hope—even when she moved to New York to be with another guy. I could have stayed stuck. But if I'd have stayed stuck there, I'd have never met my wife and I'd never have the life I have now. It's not like I don't understand what it's like to pine for somebody. But what I realized was [she wasn't] into me."
