It doesn't make any difference if you have money or if you don't have money. If the two of you have different spending habits, different savings goals, different thoughts about investing, or different fears about being poor, then financial problems will eventually surface in your marriage.
It's quite possible that the one making the most money may try to control all the finances. Sometimes a power struggle concerning money will creep into your marriage.
"Like success, money is an emotionally volatile issue for most women. It's probably the most complicated relationship we have—and the one that most controls our lives because we let it." ~ Sara Ban Breathnach, author, Simple Abundance.
How Many Checking Accounts?
Financial planners generally recommend that individuals in a marriage relationship who have disposable income should each have their own account. They can then save or spend money as they want without having to justify the expenditure or feel guilty about spending the money.
Importance of Talking About Finances in Your MarriageEven though it is difficult sometimes to face into your feelings and thoughts about money, it is imperative that a married couple make time to discuss their finances and to make decisions together about budgets, short- and long-term goals, and investment strategies.
Examine your childhoods and expectations about money. Respect one another's values and find ways to compromise in how you will deal with your financial differences.
"Money is one of the biggest generators of problems, arguments, and resentment in long-term relationships. Couples argue about spending, saving budgeting, and disparity in earnings. When couples have difficulty with money, it can lead to financial infidelity: out-of-control spending, lying and hiding finances; which can destroy the relationship. Overcoming money problems together and working as a team will strengthen the bond between you, and help you create a healthy, lasting partnership."
