In today's world most couples, whether married or living together, work. In the OLD days yes the men were more responsible. But the woman stayed at home so the need for the woman to pay was not a question. Love and relationships are about give and take. About making each other happy.

I am a stay at home mom and wife. I take care of our children, cook, clean, run all in the home front.
My husband works and supplies for the family.
When you make a commitment to live with some and live as a couple then that means sharing everything except for prior debt. Your debt is your his is his. When and if you marry then it all becomes both.
If you both work then you both would pay and you would both help with cooking cleaning and household chores. If the cats are yours then you pay.... if the cats are his then he pays. If they are both then you both pay.
If he is renting the home and you move in then both pay. If the home is purchased and only in his name then he pays.... you pitch in for utilities and such. If you are indeed a stay at home housewife then you would have no income to contribute so why would he ask you to pay your fair share?


If you live in different homes then no question.... you pay your home he pays his....
If you invite him over for dinner then you pay for the groceries.
If he invites you out then he pays. If he want you to join him for a car show let him pay.

But just because you are a woman does not give you the right to assume that MAN must pay for everything. If you are living with a man outside of wedlock then you are indeed a product of the late 20th and 21st Century. You cannot have your cake and eat it too. If you want the man to supply all in regards to finances then you better get married ... take off your shoes and get to making baby.... and cleaning..... clip the coupons......
Why ever should a man that your are not married to be responible for you?
