I think this is terrible advice, because her dumping her husband when HE doesn't want that would be just another way that she is taking all the control over what happens to him in his life away from him. Loving and living with an addict is chaos and one of the most painful parts about it is never knowing what is going to happen next, and having absolutely NO control over that.She should do it anyway to prevent him from going threw this again…..then again…..then again…..
That's what creates codependency in people who have relationships with addicts.
So for her to dump him, "for his own good", when HE hasn't chosen that, is another way that he would be victimized by her. At this point, the best thing she can do for him is to LET HIM CHOOSE what happens to his marriage and life.
Now that the horror of her addictive behaviors are over, his mind and heart need to adjust and recover, before he can even comprehend what happened to their (his) lives. He may very well decide he doesn't want to be married to her. But in order for her to stop traumatizing him, HE needs to make that choice, not her.
