Why don't you have another choice? Are you afraid you are not gonna get married again? Are you financially dependent on him? Have you talked to your family about this abuse? Have you told them how unhappy you are?
There is not a single reason for you to stick with this guy. I know the way our society and culture works. But whats more important to you, image or your own hapiness? Are other idiots so important to you that you are willing to go through hell? Bring your child into this hell? There is only one person that understands you and only one person that can help you, that is you. Trust me, once you have decided to help yourself everything else will fall in place and I am sure your family will be there to support you.
I know its a difficult step to take or to even think about it. But you can't sit there and hope that things will change, you have to make them change yourself. Has he even shown any signs he will ever change? Or is it just all wishful thinking in your head? Have you even ever sat down with him and told him how you feel? How you want him to treat you? How the things he says hurt you?
i would like to clarify that v r talking abt the Pakistani families where if u disscuss a respectable family brought up, the parents will try their best to have reconciliations and once a girls gets married, she sticks to it till the death. she has to somehow or the other cope and bear all the circumstances with patience. the 2nd marriage concept needs a lot of time and at times things get worst so it all is simple mere wording if v talk about the pakistani marriages. i have seen many well-groomed and educated families who advice their daughters to compromise and don't want to see them back home, the family pressure, the society and friends pressure,fear of the elders as they often quote their experiences, and god knows what else. v have to admit that it is a stark and bitter reality that v r affected and run by them in our family matters.
