First off, if you need a woman to help you pay bills, you shouldn’t be staying with each other in the first place. You should never rent an apartment or home with the thought process of wanting someone to help you. If you are going to stay with your girl, you have to setup your finances a certain way. The way you do that is in the event you and her happen to breakup, you still should be able to keep up with all the bills.
Now even though I wouldn’t require my woman to go half on all the bills, I will make her pay something though. For example, when I was with my ex, her contribution to bills was to give me half the rent. After that, I paid everything else, which she paid her individual bills (phone, car note, insurance, etc).
So remember kings, if you need a woman to help you pay bills, odds are you shouldn’t be staying with each other in the first place. As the man of the house, she is looking at you to see if you can handle everything. If you need her to help with bills on a regular bases, how do you think she will view you?
