from my broken home to yours. HELP

It's no secret that my husband is both emotionally and sometimes physically abusive. Most days it's not that bad and I am able to overlook his immature, ignorant, hateful, ways. Last night wasn't one of them. In an argument about his mother, he chose this time to say that... I will never be above his mother. He will never take my side when it comes to his mother. And I am nothing. I offer nothing. I bring nothing to the table. And he does not give a shit if I were to walk out and leave today, and he corrected that, to stand and say, he actually wishes that I would just quit being so pathetic and leave, so that he could finally be happy. Needless to say, I slept on the couch last night and cried myself to sleep. Today I woke up feeling so used broken and down. I thought I should look up an article or maybe buy a book to help me understand why it is that I continuously willingly stay with this man. Why do I hurt myself in this way. Why am I so weak and as he says pathetic. It's more than the money and the big house and the two kids with a third on the way. Why do I make excuses for him. Why do I consider being talked to like this every single day....okay. ?????? Well, in my search via google attempting to find answers to these questions, I came across a test. A test that asks pretty generic questions about abuse to determine what type of abuser you are dealing with.... here I was sitting feeling sorry for myself answering these questions.... "Yep he does that! OH YEAH he def. says that to me.... " so on and so forth. And as I got further down to some of the questions, The behaviors and words started to seem familiar but not coming from him. But coming from me, towards my 10 year old daughter. Now, not that I'm justifying or belittling emotional abuse, I want everyone to understand, I do not hit my child. Or physically harm her in any way. But I never realized how hurtful and unkind my words to her are and have been for so long. " are you stupid! ? " " what the hell is wrong with you ?" The list goes on. And while I was sitting feeling sad for myself and the way my monster of a husband treats me, I realized that I had become a monster to my own child. It's an impulse. It's a reaction. Its words that come out of my mouth with a tone that I don't even realize how hurtful it is. Until I pictured how I feel when he treats me that way. And I'm sat here disgusted with myself that I made her feel this exact way.
