pablo speaks that which you don't want to hear, and he is right.
once you are joined in holy matrimony, your credit becomes her credit, and vice versa.
at one point, my wife and i kept our finances separate. this worked well, as i paid all my bills on pay day, then lived off the rest.
then i got lazy. (this was actually better for me). now i sign my paycheck and give it to the wife. we have a certain amount that goes towards bills, mortgage, etc. i get the rest of my check minus our joint bills. we now split stuff 50-50. we were socialist for a while as well (bills were paid based on the percentage of income each of us made, because she made a lot more than me). the majority of my remainder goes into my savings, and i drink the rest (barley pop) or spend it on car care products.
anyway, your best approach may be to sit down with the s.o. with a stack of monthly bills and pay stubs, and write up a budget. open a checking account for bills. open a savings account. open a christmas club account. together, go see a financial advisor.
my wife and i have argued about money only when i did something stupid, like bought a motorcycle without telling her. for instance.
we are lucky. we make good money, had no college debt and no credit card debt. we don't have kids, and we don't try to live beyond our means. you just have to get used to having $x in your pocket and living on it for a week or two.
