My girlfriend believes she should not have to help with any bills

My girlfriend (25 yo) believes she should not have to help with any bills in the house because I make more than her o, my girlfriend started a business 2 years and during that time I made sure I covered all bills, expenses, groceries, etc. It’s been 2 years later now and I gave her more than enough time to save some money for herself. Recently we have been kicking off because I asked her to cover the hydro bill ($100 a month) while I cover rent ($2350), internet ($70), and groceries ( Roughly $500). As she believes she is a woman and women should not have to pay bills, and that I make a lot more than her so I have nothing to worry about. What should I do? To add on to that, she does not want to help with no finances, but believes I have to be taking her out to dinner, parties, spending money on her, etc. Edit: Thanks for all the input guys, think I know what I need to do. Gonna send her a link to this thread too! Never thought I’d get so many messages!!
