For the Ladies cohabiting ! (Living with boyfriend not married). Split 50/50??

Scenario: you live with your not yet married boyfriend of significant years. You work part time and earn significantly less than he does whereas he works full time and makes double. You split the each and every bill 50/50 but only you do the cooking and cleaning around the house. This is obviously unfair. What would you do? Don't necessarily choose the "right answer" there is none. Just curious about what people would do.

I wouldnt mind doing the cooking and cleaning if he paid more so I can be the semi stay at home person. But to do that and pay 50/50 when you barely have money is like giving them cake and them also eating it. Poll or comment. No rudeness please, if you can't seem to hold off on rudeness please jut don't comment or the comment will be deleted.
