Health, why do you need examples of mental abuse? Are you quizzing me or do you want to deny the existence of mental abuse?
I recommend the book “The Shame Borne in Silence – Spouse Abuse in The Jewish Community” by Rabbi Dr Abraham Twerski
Twerski discusses both physical and emotional (=mental) abuse.
{Borne is the past participle of the verb to bear. The illiterates think the title refers to shame born in silence}
