Just to begin with….I do feel sorry for what you are going through…
I may sound little rude and unethical to you…but i have some suggestion to check out a fair history of the husbands family along with the neighbors and other close friends to the family.
Know more about the your husband…his near past activities…so that you can find some sort of reason or arguments to justify the action he is doing to you…..?
Based on this no matter what you discover do take some bold action that will protect you and your husband, and be in touch with some trusted people from your family and discuss that action your to take.
Dont give up your hope….everything will be fine……….
