If your husband has not already been found to be an abuser, or if there is no current court case regarding his alleged abuse, you need to bring your concerns to the authorities. And you should do so ASAP. You then should strongly consider filing for divorce. As for then filing for supervised visitation, you need to seek legal advice before going to court regarding custody. Consult with an attorney who specializes in custody matters to find out what you would have to prove to get the visits supervised and how long supervised visits would last, based on the facts of your case.
