I just wrote something about their marriage as a matter of fact. He's saying how he knows how spoiled she's always been, but he loves her anyway. She's not as much of a jerk as it might seem on the surface(her own father lost everything when she was ten and she knows what it's like to be poor, money is one thing she does not let affect how she treats others).

She was far worse in the past, and his love changed her.
