The Cold, Hard Dating Truth

After reading Greg's book, Kathryn dumped her deadbeat boyfriend of four years. "[Before you read] the book," Kathryn says, "there are certain guys that you give a lot of slack to—and some guys you throw the whole rope to. … We're all professional, smart women. We know how to go after things in work and business. We get the job. It's hard to turn that switch off when it's personal."

Kathryn has also realized that if a guy isn't into you but you hang on to him, he's not to blame for your unhappiness. "It's not the guy's fault at all," she says. "It's something we create."
