An abuse victim is living in the midst of confusion; you can provide clarity. Let her know that she's not to blame. Remind her that she's not alone. She may happily share that her abuser has said he's sorry and has vowed to never to do it again. Make it clear that those kinds of assurances are simply another form of manipulation [source: CRAA]. She may have bought into the belief that he just needs help and she's the only one who can help him. Assure her that such rationalization only puts her in danger [source: HelpGuide]. Stand firm and help her to stand firm, too. If you waffle, it will be more difficult for her to see the abuse for what it is.
You may think you sound like the proverbial broken record, but your consistent and repeated direction could be the only messages she's getting that don't change. That gives your guidance credibility.
