Is it normal for a victim to still read abuse books or websites when things are going well so that he or she can stay one step ahead of the abuser?

Of course, though if you're still having to stay one step ahead of the abuser, then things probably aren't going that well. An abusive relationship has highs and lows, calm periods and periods of active abuse. But it's still an abusive relationship. If you're in such a relationship, talk to a professional. They're there to help you find alternatives, whether it's healing the relationship or helping you take back your own life. Yes but you eventually wont be able to keep up. The only way to stay one step ahead of him for good is to leave. Remove yourself from him and he has lost all power.
