But listen to this and listen well: In 28-33% of all domestic violence MURDERS, there has been NO PRIOR PHYSICAL VIOLENCE.
So before you dismiss the evil of abuse as "not that big of a deal because he doesn't hit her," take the above statistic to heart. Abuse, in any form, should ALWAYS be taken seriously.

(Note: In all of my posts I use "he" for abuser and "she" for victim for simplicity and because, in the majority of cases, the abuser is male. But it can be the opposite with a female abuser. Dynamics of abuse can also happen in same sex relationships.)
