I'm sorry for you. Just leave, he's no good for you. The attachment will fade away...it's like a Stockholm Syndrome or dependent personality disorder or something.

My parents beat us up for most of my life. Our self esteem was so demolished that we were led to believe that we couldn't survive on our own. Once I got out, I never looked back. We are damaged goods. It took awhile to learn to love myself and that they were wrong. I wish you well.
