You have to be understanding, non-judgemental, and compassionate. Respect their choices and be an active listener. As a domestic violence and sexual assult conselor I find by listening to them more the better understanding i have about their situation. Victims need support, need to be educated on what violence is, how to have healthy relationships, how to value themselves, finding their own strenghts, develope coping skills, becoming independent and developing self confidence again. You can guide them and give them options, but never make the decisions for them, You are trying to empower them into making there own decision.
