Is the topic of money touchy, or how you interact with W when discussing money? It reads like you yell when discussing money and when dealing with the kids. Could S12 be reflecting a learned behavior?
Where were you emotionally during this breakdown of R? Very happy? Is the yelling a function of your unhappiness?
Finally, don't let W drink and drive with the kids (and truly, even without the kids). Even if it means making W extremely angry and W threatens to leave forever. Call the cops if needed. You are right, you can't stop her from drinking, but you can keep others safe.
