On the one hand, yes it wasn't her fault. Even if she did dress provocatively, that's her right.
But then again, I'm sure that dentist worked very hard to establish that practice. He had to earn excellent grades to get into dental school, and 4 years of dental school isn't easy. He might have also had a few years of fellowship training.
After all of that, he had to take a big financial risk and establish a practice, which I'm sure he had to work very hard at to build up. This is his sweat and tears, his money and his practice. If he doesn't feel he has the willpower to resist this woman, he should be able to can her and hire another one.
That being said, it seems like the guy is definitely a complete b*tch in his household. This is almost certainly a move initiated by his wife. But, that's probably what ultimately allowed him to avoid penalties from the court: "but a woman's marriage is threatened! We can't have that!"
