Why did Ruth Ellis kill her lover?

Ruth Ellis killed her lover, David Blakely, on April 10, 1955, due to a combination of emotional turmoil and his abusive behavior. Ellis had been in a tumultuous relationship with Blakely, who was often unfaithful and violent towards her. After a particularly distressing incident where he rejected her and made her feel humiliated, she shot him outside a pub in London. Her actions were fueled by a desperate need to escape her tumultuous relationship and the pain it caused her.
