I'm sorry you are going through this- but always remember, better divorced than dead (I know that sounds harsh but it's true).
I guess it's too late to say surround yourself with your loved ones- but I will totally stress that you go to counseling (I am not sure if you are) and take a BIG break from relationships right now for at least one year.
If anything, take from this something to learn, I bet looking back you realize that there was signs of abuse that you ignored. My mother stayed married to my father for OVER 20 years and took the abuse- because of him she's deaf in one year (he beat her very badly) and her one regret was not leaving sooner.
I think you'll be okay as long as you take this time to learn to love yourself. I guarantee one day you'll find a man who loves you and treats you right, scar and all
*hugs*
