Dear AnxiousAsUsual:

Aggression does express itself in more than one way, such as a loud voice. The silent treatment for example is a very silent form of aggression.

You can learn a whole lot about your boyfriend by  knowing more about his relationships with his parents, past and present. I suppose his father who was abusive toward him lives in another state, where you used to live, correct?

What do you know about the nature of abuse he suffered from his father and about current mending of that relationship?
