This does mean accountability to one another, based on shared financial goals and mutual accountability. Work out a budget together. You write your own checks and consider taking on the responsibility of paying monthly bills or at least sharing bill paying with your husband equally. You might also try being more proactive regarding your own behavior to money in your relationship. Consider paying for groceries when you go the store together, and make an agreement that when each of you spends money from your joint resources, you need not get consent of the other if it falls within the budget you designed together.
Some couples make agreements to consult one another for purchases over a certain dollar amount.
Create the agreements and rules by which you relate. Take your fair share of bill paying and contribute to financial planning. The fact that you already rely on your husband to drive may make you vulnerable to letting him do things for you that later make you feel passive or childlike in relationship to him. Accepting equal responsibility for sharing resources builds in accountability on both sides. And look out, passion can be dampened by parental dynamics in any relationship.
