Abuse.

I'm really in the need of help. My mother has been in an abusive relationship with my stepfather for the past 5 years (They got married 2 years ago). It's not physically abusive, but it often gets to a point in which he goes into these rages whenever he's drunk or sees my mother with male company (or with friends in which she had to cut off because of them). He's really just emotionally abusive to the point in which she's now diagnosed with depression because of this, but yesterday was when my sister and I was fed up with it (I'm 18 and heading off to college next month, but I don't want my mother or family to deal with him no longer. The situation is bad to the point in which I actually want to physically harm him, which I never wish to do to anyone). He constantly disrespects my family, especially my sister and I (He's even called me all types of stupid retarded bitches during a fight in which I had to call the police on him since he was violently drunk after accusing my mother of having an affair.) The shitty part is that he's had more than 5+ charges against him on domestic violence, but his record was recently cleared. I'm fed up to the point in which I actually want to physically harm him, but I'm not that type of person. All I could do is really alert some of his close relatives to make them aware, and all because it actually scared him.

Other than that, I don't know what to do.
