What is the Sharia ruling concerning a wife who refuses conjugal relations with her husband and procreation, abuses him verbally and physically, and prevents him from financially assisting his parents? And what are the consequences if the husband hits her after her latest abuse and her request to distance herself for psychological healing?

This woman is recalcitrant and of very bad character. You must follow the steps for addressing recalcitrance. If she is psychologically unwell, then efforts should be made to treat her. She should be advised to abandon her bad actions. Otherwise, it is permissible to inform her family and those who have the ability to advise and deter her. If she does not desist after all of that, then you may divorce her.
