I borrowed it from the Brave Battling Babes Bus...
Being stuck in an abusive relationship is the exact same thing as being addicted to alcohol.
To rid ourselves of these life threatening afflictions we need will power, strength and to remind ourselves that we are worth the fight.
Whatever it takes. 
Grace, you are so strong, so awesome, you don't deserve to be in anything less than a loving appreciative relationship. Thank GOD you complained! Thank GOD he left. You are stronger for it!
GG, what is it going to take for you to break the cycle? if this guy threatens to leave, don't panic, let him go.
I know I am a fine one to talk. H is still in the building, but he is powerless and he knows it. I won't let him even look at me in a funny way. I know he is not strong enough to keep me down, I know what he is and it's been devastating for him. Now that I see though him, he has nothing.
That said, he stalked off the other night after a row, and my stomach still twinged. I had to tell myself not to care, tell myself to get used to it.
5 mins after he had gone, I was pleased he was out of the house.
GG, tell yourself whatever it takes for you to regain your sense of self. You know what is going on is wrong, so stand up for yourself TO YOURSELF if nothing else, and speak the truth to yourself.
You have been fed this crap for ages, now is the time to stick to the truth. Sure it hurts, yes we beat ourselves up, but recognise what we are doing, be conscious of it and make sure it's kept manageable. Learn from it, don't allow it to swamp or over power you.
One day this relationship will go (mine) and one day may be so will yours. We will then both be free to breathe air that is untainted with insecurity, fear and control.
Don't be frightened. That's what he's banking on. That's his only weapon, your own fear.
