What advice would you give to a guy who has just started dating a girl that has been abused?

How does a guy handle a girl who has been abused and neglected by her parents? The main concerns revolve around her patterns of major depression, self harm and cognitive distortions that are the result of forced and protracted intrafamilial deviance stemming from extreme paternal violence & domination along with maternal aquiesence and passivity. She was subjected to a full spectrum of deviance and abuse yet remains highly articulate and gifted both musically and poetically and shows a very high level of intelligence. How does a guy successfully navigate this situation so as to successfully cultivate this new relationship with her (they are both in high school). What resources and information are available to them?
