I look at it this way...either she is going to have an "epiphany" and realize that she has almost f*cked up the best thing that has ever happened to her and get her mind straight on reality or...she will blow up and meltdown ultimately ending up on the streets or in a mental institution.
.....She on the other hand has a violent temper and will on occasion throw things while she is screaming and yelling...she squeezed her finger nails into my right arm over the weekend and brought blood.

So basically you are responsible for her happiness or else?
You have the right to live your life without having to put up with bad behaviour.
You deserve to live without the fear/threat of her emotional attacks/outbursts.
You can't control her, or what she does, but you can control what you will or will not allow in your life.
She needs to see a counselor/psychologist/mental health professional.
Is your wife overly dependent on you?
