Simple. He fulfills an emotional need that she feels she hasn't or can't get from you. In this case, he's not judgmental. She has no REAL ties to him so it's an emotional freedom for her.
Meanwhile, because you were protecting your family by showing her how foolish she was, it made her pursue the fantasy even more.
It's like a kid in a candy store. If you tell the kid they can't have something, they're going to want it more even though they know it's going to rot their teeth. And no matter how many times they say they hate their parents for not giving them the candy, they don't leave the parents.
It's a simple analogy but it seems that's how your W is. The more you tell her she can't do something, the louder her tantrums become. That's why it's important for you to remain the adult and protect your assets while she goes off and burns out her fantasy.
