My story - I'm afraid to leave my mother alone with such a father

I am 18 years old. I live with my parents, study in college, 3 year, I finish this year. There are seven of us in the family - Mom, Dad, I (the oldest), brother, and 3 sisters.

From the outside everything seems to be good, but it's not. My dad, when very drunk, beats mom and us when we want to stop him. But when he beat me and my mother tonight, this was the last straw of my patience.

It was a normal day. Neighbors and my parents were sitting in the courtyard, celebrating his neighbor's birthday. They sat for a long time, drank. Night has come. We all slept, suddenly I woke up at night from the fact that my mother can not put my father to bed. Dad as a sick man stood and looked at his mother, my mother persuaded my father to go to bed for a long time. But Daddy and I stood there. When my mother once again told him to go to bed, my father beat my mother, then we left the room and decided to stop my dad, me and my sister. We stopped as best they could, then my mother managed to escape to the street and hide from the pope.

We told my dad that we are tired of living like this, since childhood everything has been so, constantly quarreling, beating, etc. We said that we do not want this to continue, because my little sisters are still small, they have a child's psyche destroyed, they see it all, when I said this, my dad hit me in the face, and went out into the street to look for my mother and beat up. We sat at home, everyone was in fear sitting, we prayed that my father did not find my mother and that he did not go home. He went home and began to destroy everything, saying that he built this house, and that thanks to him we live here.

Then I got tired of it all and told my sister to go to bed, then I went to my room and closed the door. Dad followed me, and when I closed the door, he broke the door, then when I opened the door, he hit me in the face so hard that I fell onto the floor immediately. And the little sister came after me and started to stop my father, Dad and she hit. We started to cry. And again he went out into the street, and after a while he went home, and told my sister that she would go to bed, I told my dad that her bed and room were there, he started beating me, asking "where is it?".

I could not resist the pope, because I was weak. My sister cried and begged him to stop, but my father did not listen, and so he continued to beat me, I just sat there, I could not cry or fight back. Then the pope began to insult us, to say that we are ungrateful, and said that we make him guilty in everything. We were silent. Then my dad left for the street, my mother went through the window and hid herself at home. We all went to bed in the morning, somewhere at 6 o'clock. I silently cried with helplessness, and decided for myself that my father would never forgive, his actions do not justify anything, I was thinking about how he would look us in the eye. So the night passed, and the morning came, and now he walks so and pretends that nothing has happened.

I'm tired of living like this, falling asleep at night in tears and waking up as if nothing happened. I have a boyfriend, he is not like my father, he loves me very much and I love him and we want to get married in a year, but after yesterday I do not want to marry, I do not want to leave my mother with such a father. If I marry, I'm afraid my mother will not be protected. Previously, in such situations, I thought and reassured myself that someday I would leave this house, and this would all end. And now I do not want to leave my mother with my father. My dad, when he does not drink good, and when he is drunk, he becomes like that.

I do not know what to do? When he beats Mom and us, I can not go to the police, because he's my dad, I'm afraid. This can not continue, I'm tired. Now I'm in a difficult situation, what do I do not know.
