Welcome to the forums– I'm so, so sorry to hear about all that you've been through with your husband. It should go without saying that every part of this is COMPLETELY unacceptable behaviour on his part and you deserve better, no matter what the other circumstances are. This is not someone who has your best interests at heart and in my opinion is not worth a moment of your time, energy or consideration.
Of course this is easier said than done once you have built a life with someone and become intertwined with them. Without knowing many specifics of your situation, I would urge you to first and foremost cut off contact with him and his family and contact an attorney if you can afford one. I know little about divorce law, but in many jurisdictions you do not need your husband's consent to file one. May I ask where you are now, if you are physically safe, and how you are doing in terms of resources?
I hope you'll stay with us here on the forums to chat a bit more and share more of your story if you're comfortable. This is a totally safe and non-judgmental place.
