Ah, the tinder thread.
As for your problem, ghost her. No contact at all. They get the hint after a week or so,especially if they are still on the app.
Future advice, I agree with above, cut ties at first signs of crazy. Sex is better with crazy ones, but not worth it in the long run.
I haven't posted in a while, but I banged out a 37yo fitness competitor mom last night (3 times, "finished" in her mouth the 3rd round.) She cooked me bison chili and made me toffee. it was the second time I've hung out with her and have spent exactly $0 on her.
