Yes, if she is narcissistic their MO is to accuse you of doing what they themselves are doing. So in essence they are actually telling on themselves not realizing it. The person that mentioned this to you is actually probably one of her flying monkeys.

Also, if there is some guy you already know she is just using him. This type of individual doesn’t change. They are always “users”.

Your wife likes to drink, she probably goes to bars/clubs/casinos to pick up guys. Narcissists like to hang out in places they can pick up or prey on for quick supply.

Narcissistic individuals live delusional lives.
