Need expert help here. what are the characteristics of an abusive person?

Sense of entitlement: Many different people here will give you many different answers, but here's mine. The abusive person thinks the target is responsible for their own happiness. Blaming, unrealistic expectations, belittling, limiting access to others, blowing up, apologizing, begging for forgiveness, waking you to scream at you are all part of the picture. It's a cycle that leads to most domestic homicides. Beware.
