She might not come back if she has truly converted to Christianity or because of her age, or because her body no longer has the beauty it once did.
Aside from that, it's quite possible that she still does private shows for select clients, because the woman does it not only for money but also for exhibitionism and to feel desired. Showing herself off to strangers, even virtually, is still a way of betraying her husband; it gives her brain a surge of endorphins/adrenaline, and that's addictive. A normal marriage is unlikely to give her those strong emotions.
I once heard from a prostitute that a prostitute never really stops; she might stop for a while, but at some point she comes back.
I know the word prostitute can be strong for many, but in a way it's a mild form of prostitution.
