Okay, so his mom died when he was like six in January, so now hes being a complete douche. He had a knife last night while we were laying in bed and he was like trying to cut himself and he was going to cut me, so I took the knife away and we had a serious talk and I started to cry so he stopped. Then he got happy and decided he wanted to have sex. Like an hour after that we were in the living room in the basement and he took his knife back and when back into his room and I told him to calm down and he said he was calm and I replied back as "yeah and Im Obama's daughter". So he got really pissed and I went to bed. He woke me up and at first was apologizing to me about being a douche and hurting me and whatnot. Then he started flicking my cheek and that really pisses me of. So we went to his room so I could kick his ***; and he was really beginning to make me mad because he kept hitting me in the face and "choking" me.
So. I would like to know what to do in this situation?. Im only a teenager as well as him. I don't need this ****.
