I see all the varying opinions; but, it a matter of perspective. For me; someone who has basically lived this reality; it was telling. "Hurt folks, hurt folks!" The husband lived, what he knew; and, his wife thought she could fix him. They both needed real counselling, to break through their own misconceptions.
I know this hurt. Because my ex-husband did not have the benefit of a full nuclear family; he resented me. There were many red flags, that I ignored, because I "hoped," things would get better. I hide the abuse, from my parents; because I didn't want to admit, that they had been right in their warnings about him.
None of my family, attended my wedding; in the hope, that I wouldn't go through with it. Of course; "stubborn," me; ignored that red flag.
I finally gave up, when he threatened to set the house on fire, if I tried to get it in the divorce. I didn't believe him, until he came in and poured gasoline on the bed; and, set it on fire! (With me in it)! You can't fix people!
Minus the radical drama; this was an excellent portrayal, of the lies we sometimes tell ourselves!
