What should a wife do who wishes to separate from her husband due to his ill-treatment and failure to provide for her, but fears divorce and its impact on their adopted child, while also seeking not to relinquish her right to separate?

The husband is abusive by stirring up problems, mistreating his wife, and failing to fulfill her rights. Each spouse must fulfill the rights of the other. The wife has the right to financial support (nafaqah), and if she helps her husband or provides for it, that is a voluntary act of charity and kindness on her part. The wife should be patient and supplicate for his rectification, seeking assistance from those who can advise him. Divorce is a right for the harmed wife, but it is not recommended to resort to it except after consulting wise individuals and discerning what is in one's best interest. Adoption (tabanni) is forbidden, and it is not permissible to attribute the child to them, but fostering and caring for him are among the best deeds.
