DO women actually pay the bill on a date?

I have been to 4-5 dates so far with 3 women. None of them even offered to pay for the date or even 50:50. Although the dates werent expensive (less than 500). Yes the sample size is small.

Even in my colleges days, alot of women (even as friends), avoided paying bills.

I hear alot of women online saying they pay on dates or 50:50 it. Just curious
