Please never let anyone ever tell you that YOU have to change in order to prevent him from abusing you, it is simply not going to work. Abusers are not reasonable people or they would not abuse you in this way. We all do things that anger our love partners from time to time, but reasonable people can talk about those things and don't have to throw a temper tantrum, scream and holler, call the their partner names, beat them, or whatever they do. You are a precious human being and you do not deserve to be mistreated. And to have it.
Emotional abuse is just as damaging as physical abuse.
The only difference between the two is with physical abuse you are wearing it on outside for the world to see and the other is felt deep inside. Your feelings will fester and grow into resentment, anger, depression and cause you to feel as insecure as they really are. People cannot see the bruises on your heart. Don't allow an abuser to drag you down to their level. When need goes away, choice shows up.
