But it wasn't just any modeling job. Erica did softcore modeling for a famous internet web site!
Worse, she earned enough for the next month's rent, just from that one modeling job.
Afterward, she was very proud of her ingenuity and showed you, on your laptop, some of the pictures.
But with your conservative upbringing, you couldn't accept her modeling as a good thing, especially when you saw the pictures! They turned you on, but you didn't want to admit it. So you yelled at her that she'd become a whore, which started a huge argument.
The argument ended badly, with her smashing your laptop during the heat of it.
And you called off the wedding.
