Abuse can run in families, so maybe there are other family members that are also abusive. You need to research personality types, e.g. psychopathic, sociopathic, covert narcissist, overt narcissist in order to better understand how to respond to the abuse. Most experts advise practicing 'grey rock', learning not to rise to goads and provocations, and distancing oneself (as far as going 'no contact', which is permissible if you are being harmed.) Unfortunately it is very hard to get abusers to reform. It is not your job to do that. Youtube now has thousands of videos that advise people on how to deal with abuse. A systematic and detailed study of this from an Islamic perspective still needs to be made.
