Quote from : Why Does He Do That?: Inside the Minds of Angry and Controlling Men Book

YOUR ABUSIVE PARTNER DOESN’T HAVE A PROBLEM WITH HIS ANGER; HE HAS A PROBLEM WITH YOUR ANGER. One of the basic human rights he takes away from you is the right to be angry with him. No matter how badly he treats you, he believes that your voice shouldn’t rise and your blood shouldn’t boil. The privilege of rage is reserved for him alone. When your anger does jump out of you—as will happen to any abused woman from time to time—he is likely to try to jam it back down your throat as quickly as he can. Then he uses your anger against you to prove what an irrational person you are. Abuse can make you feel straitjacketed. You may develop physical or emotional reactions to swallowing your anger, such as depression, nightmares, emotional numbing, or eating and sleeping problems, which your partner may use as an excuse to belittle you further or make you feel crazy.
