What Makes the Biggest Impact?

I often wonder what will it take to end teen dating violence? What will be the straw that breaks the camel's back when it comes to ending this? What is really crazy is that it's not like cancer or some other disease we don't fully understand! It is in OUR power to end! All we have to do it just stop trying to control the person in our relationship! All we have to do is say enough is enough and to stand by that!
What do you think it will take?
