I agree with other posts,you really need to remove yourself from this situation.
The very fact that you have asked for advice tells you that in yourheartyou know that this is not right...It is typical of the abuser to make you feel as though this is your fault and tell you so..BUT,it ismost definately NOT your fault.
I too have been where you are now,and believe me it will onlyget worse..seek help to get out of this,there are womens refuges that will help you..YOU are a strong woman who DOES have the power to change your situation,abuse is all about control..take that control back for yourself.
It is not an easy thing to do,but you are not on your own in this,please get help now,don't give him another chance to break your spirit,sending you virtual hugs,keep safe.
