This is verbal assault; it is as painful (if not more than physical abuse), and can damage the immune system; most women who are abused have many physical illnesses; every time we are under stress, the body releases cortisol; cortisol damages the immune system. Try to put the blame and shame where it belongs.......on the abuser. I know how difficult it is to leave; I stayed for 31 years; The Verbally Abusive Relationship by Patricia Evans saved my life....Calling the domestic abuse hotline can also help. Abusers are angry miserable people; and they take it out on others. When he is abusing you, he is also....abusing your son. Maybe when you feel like going back with him; you can think about your son; and that might be the thing that prevents you from that. xoxo
