Assuming you are in earnest and events are portrayed correctly... you can't. She is dead set on this and thinks you attempting to convince her out of it is you being a misogynistic control freak. You should get what she is saying in writing, be it texts or emails, even facebook messages, and then go to talk to a divorce lawyer. Even if prostitution is legal in Nevada, I think it would be a slam dunk to get a divorce on the grounds that your formerly not-a-sex-worker wife is trying to become one.
