Narcissistic abuse

I have been married for 8 years and know that I need to leave. While I am far from perfect I do what I can to continue to be a good mother and good wife; the wife and woman that my husband doesn't deserve. He treats me so awful, and talks horribly about me to my children and step-children, a long with my family and some of our friends.

At times he even goes out of his way to emotionally destroy me or hurt me. I want out, but what the *** is stopping me? I want to love someone who deserves it, and I want to be someone's queen.
