Is it necessary to split a bill after the date/pay for the dishes you ate or it's simply a courtesy for the guy to pay?

Recently after the controversy Abt 370. His way of thinking and actions were quite wrong. But as a girl and someone who believes in feminism i believe that we should split the bill. So it's even or just pay for the upcoming date. Even if the guy pays for it, it's fine. Ofc if he's fine with it. When I had actually commented on a post saying that splitting is better someone replied saying that it doesn't make sense as girls put more effort and go unwillingly. I mean if you feel some kind of pressure it's better to not go on a date. Yes girls put more effort into their appearance especially before dates but we also earn and we do it cuz we enjoy it. Ik that grooming is an invisible weight put on us by spending more time and money.

But when someone pays for the bill often they feel like they "owe" us. Which isn't right. Still expecting guys to pay for the bill is just a crazy. I feel like we shouldn't keep so much expectations on them. Also just cuz they fully paid for the date also doesn't mean that they can harass or "owe" the girl.
