This is how your emotional abuser uses your own fear and/or 'wear you down' to coercively control you, your emotional abuser will use manipulative patterns of behaviour to turn you into a frightened resemblance of your former self, too afraid to say what you really think and, because you are too afraid to say what you really think, you keep quiet and 'bite your tongue' about how you really feel out of sheer fear or exhaustion until you withdraw into yourself because the situation has worn you down so much you no longer feel able to challenge because another battle, another argument and/or the prospect of their reactions, outbursts or guilt-tripping is too scary and/or too exhausting, so you say nothing because it's easier and that is precisely how your emotional abuser will divide, conquer and take control of you.
