Dad still insists on seeing the woman he cheated on my dying mother with and getting drunk and violent

My mom passed away in February and shortly after that my dad got caught with a woman that he had been seeing before she died and is a known alcoholic but has obviously gotten worse. He has gone up and down with his drinking and seeing this woman but she is not welcome at my house I have declared. Tonight is the first night that she has been here at my house after many meetings of my uncle saying im not allowed to stay here anymore because I don’t feel safe with this woman being here. Tonight she is in my driveway blocking my car and I told my dad to make her move and get out so I can at least go to my girlfriends house or aunts and he tried to kick my door down in my room and when I opened the door to try to confront him before he could get me semi-trapped in my room he shoved me against the wall and i slapped his hand down and he stumbled to the floor. Also stumbled down the stairs obviously drunk and not in a great condition to fight from my one defensive measure. I don’t know what to do anymore. For right now I don’t know how to get her to move her car so i can at least leave and go somewhere else to get away from my dad but in general I just don’t know how to get this woman out of my house so I can feel safe
