We are so sorry to hear of your situation.
Halachically, your husband’s actions were absolutely prohibited. You are permitted to delay mikveh immersion indefinitely in this scenario.
We are concerned for your safety, and urge you to seek help. There are organizations that might be able to assist you, whether by hearing you out with understanding or by helping you to change your situation. These include the Crisis Center for Religious Women in Israel, and the Shalom Task Force in America. Both operate telephone hotlines, and can be reached online or by WhatsApp..
Please do not hesitate to be in further contact with us.
