I'm not sure if there is a way to increase awareness. Right now it's up there with cigarette smoking; people know it's bad but they keep on doing it. Anyone who is being abused need only do a couple of google searches to find a shelter or some type of assistance. Everyone is also aware they can call the police by dialing 911.
The real problem is figuring out how to get someone to raise their self-esteem to a point where they will walk out of a relationship for good (the minute) they see their mate has a violent temper whether it's hitting a wall or hitting them.
Each of us gets to choose (our own) friends, lovers, and spouse. Unfortunately the government can't stop someone from making bad choices in their personal lives. I have actually heard a woman state: "I like my men to have some thug in them." Some people confuse violence and jealousy with passion and love. They'd be bored without the drama. This explains why it's common for victims of domestic violence to have a pattern of entering into these types of relationships.
We can punish the abuser, force her or him to go to anger managemet classes, issue restraining orders and so forth. However the person who needs the most help mentally is the person who doesn't believe they deserve better or could do better when it comes to finding love. Last but not least it's not smart to initiate violence by slapping someone and (expecting not to get hit back). More often than you might imagine the person who gets beat down is the person who "started" the physical altercation. I've never understood the logic of throwing something at someone, slapping, scratching or following them from room to room yelling at them in an effort to get them riled up. And if it is a man who gets slapped/hit and he calls the police to file charges he is considered a whimp! There are no DV shelters for men! http://hubpages.com/relationships/Is-It-Ok-For-A-W...
