Yeah...there's a reason why most Otome reincarnators end up as nobles or even royalty. Any world with a semblance of historical accuracy is gonna be a nightmare to live independently in as a woman.
Her reputation was all she had, and she threw that away rather splendidly. That said, it's not like she particularly endeared herself to the industry either. Every word out of her mouth was just arrogance and entitlement. I wouldn't want to hire her even without the threat or rumors. Mother-in-law is a real piece of work too. Even if the man wasn't a cheating bastard, I don't see anyone wanting to marry into that family without a boatload of money involved.
Anyway, karma is a bitch and Su Luxia punished the transgressors by letting them achieve exactly what they aimed for.
