Junior Year: Assault

So my junior year of high school i was dating this guy who i thought was really nice. Me and him were friends before we dated and i eventually started to like him. After awhile he asked me out and I said yes and we became boyfriend and girlfriend. He would come over to my house and we would watch some shows together. Well he told me he hadn't watched supernatural so I invited him to come over and watch it with me and he then started together a little handsy and he would take no or stop for an answer and he started to assault me and before anything more happened my mom came home and he jumped off and went home. For awhile I was scared to break up with him because he had been talking about suicide and I didn't wanna break up with him and be responsible for his death so I hung in their for a bit long until finally I broke up with him. He then sent me pictures of his wrist and told me he was cutting himself and I told his school counselor.
