My father has always been a dick, he left my mother with me and refused to pay anything towards my childhood yet demanded that he sees me.Recently he has been doing things such as threatening me with physical abuse and insulting my mother to my face which has lead to me self harming and feeling constantly worthless whenever I’m with him.I was just wondering if there is something I can do to make him leave me alone or allow me to move out preferably without bringing the law into it
