" Almost no abuser is mean or frightening all the time. At least occasionally, he is loving, gentle, and humorous and perhaps even capable of compassion and empathy. This intermittent, and usually unpredictable, kindness is critical to forming traumatic attachments. When a person has suffered harsh, painful treatment over an extended period of time, s/he naturally feels a flood of love and gratitude toward anyone who brings relief. But in situations of abuse, the rescuer and the tormentor are the very same person. "
