It's important to be able to talk about finances with your spouse. Learn not to react. Use the principle of response to coaching where you own it, instead of defending, deflecting, or denying. If you are stressed out, busy taking care of your children, cooking a meal, or something else where the timing is not good, then considering a better time to talk about it and schedule a meeting. After all, it's the right thing to do and it models the way for others.
