To me it sounds like you are in a good spot mentally. Keep up that attitude.
As far as what happened, take a step back, as boat said, divorcing you over beers isn't happening. Getting mad that you aren't falling apart, groveling, or doing something wrong that she can point that finger at to blame you for very well could be.
She absolutely wanted you to notice what she was doing so you'd go check. Don't let her know it worked. Don't bring a thing up.
