7) Come clean about financial infidelity — and figure out why it happens.
Even if you only have eyes for your partner, you're probably guilty of financial infidelity — being less than honest about money. Maybe you have a secret stash of bills or tell a white lie about how much something cost in order to avoid an argument. Whatever the case, you can't afford to let distrust ruin your relationship. Come clean about financial infidelity and don't let it happen again. Most importantly, figure out the real reason why you weren't honest in the first place. Take the quiz: Are You Financially Unfaithful?
8) Don't put one person in control of finances.
One guaranteed path to financial infidelity: putting one person in charge of finances. Sure, one partner is inevitably better at math than the other.

Both of you need to know about — and maintain control over — the money coming in and going out of your accounts.

The 5 Money Personalities encourages couples to have a monthly Money Huddle, which is not to be confused with a bookkeeping session. Instead of paying bills together or one partner filling the other in, it's an open conversation about shared finances and goals. Once you and your partner are on the same page about numbers, it's time to talk emotions. How do you feel about your finances?
