To all those posting un-supportive comments: until you've walked in her shoes please don't assume how you might react in a similar situation.
@Milosunshine you are very brave to seek support. Huge well done for taking the first step to a better life for you.
This is crucial. Listen to the part of you saying this is wrong. That part of you is right, but the more you make excuses for his behaviour, the smaller that voice will become until you no longer hear it. You will eventually only hear him and take responsibility for his grotesque actions. You will blame yourself. You will count the ''good'' things and try to convince yourself they 'out weigh' the horrible ones - you will eventually accept so much that you don't realise it's all horror. A relationship is not a zero sum game, that so long as it net's out its healthy.
Please do not under any circumstances seek to 'stand up'' to or challenge this man. The pillow will turn into a fist I can promise you that.The fist will turn into worse. Before you know it you will wake up on the floor and wonder how you got there. It will be because he hit you so hard you became unconscious. If you have yet to have children with this man, whatever you do please do not bring a child into this situation. You will never forgive yourself. The hallmark of such men is that they have no boundaries, they will manipulate people's perception of you, call you crazy, and ultimately make you doubt your own sanity. Others may well see him as a perfect husband, and recoil in horror at the suggestion he has done any of these things. Again, a hall mark of such men, they seek to isolate you so that you seemingly have no where to turn.
It is not easy to leave, and stay away, but it is possible and the only way. Such men DO NOT CHANGE. They may promise to, or behave normally a lot of time but they do not change. There are people who can help you - Women's Aid, the police. Women's Aid will help you even without you ever giving your name. It will take time, and you may decide to stay for now but it is never too late to leave or take steps to protect yourself.
I do hope the many supportive posts here encourage you hold onto the fact that your gut is right, and that hatred is the only natural response to his behaviour. The hate passes (eventually) and is replaced by indifference even pity for such a man.
