My mother could show affection and say kind words when she wanted to . . . she would abuse me, then the very next day hug me or tell me how I was her baby and she loved me blah, blah. I think it worked like any abusive relationship . . . a person feels trapped, nowhere to go . . . they are abused and then the abuser reins them back in with kindness and the person being abused settles, not quite thinking about the next time they are beat etc. just relieved the abuse is over (for now).
