She wanted that noise. Shyt like swooping in to remove a woman from a situation in that fashion does nothing but contribute to the lack of accountability that gender struggles with. Now, lending a hand to help escape an abusive situation or whatever is one thing, but just seeing "claimed" individuals and trying to snake in there is a damn snake move does nothing to teach a lesson.
That lesson: You made a bad choice. It's on you to process that, deal with it and become better for it.
I reiterate, it's never justifiable. But frankly, I believe that women typically can't be stolen from men. They are persuaded to give themselves away due to a mix of random circumstances that make the new option seem superior.
