" We all have a limit. What we’re willing to put up with before we break. When I married your father, I knew exactly what my limit was. But slowly . . . with every incident . . . my limit was pushed a little more. And a little more. The first time your father hit me, he was immediately sorry. He swore it would never happen again. The second time he hit me, he was even more sorry. The third time it happened, it was more than a hit. It was a beating. And every single time, I took him back. But the fourth time, it was only a slap. And when that happened, I felt relieved. I remember thinking, ‘At least he didn’t beat me this time. This wasn’t so bad. "
