Your son now knows she is trying to bully him. The problem with what he did was that she will twist it into her being the victim.

I have experienced a person invading my personal space while drunk and angry. Then when I don’t react the way they want they go into a rage. What they are doing is having a toddler like melt down. Then they rewrite their behavior playing the victim.

What is concerning about your wife is how this group of friends are misguiding her and she is mirroring them. This is what you are seeing when she says you are doing or have done things you know you never did.
