Help? Sexual Assault Advice

When I was 16 someone I thought was my boyfriend was actually just using me. He would kiss me and stick his hands in my clothes even if I said no. And he tried to take my clothes of to have sex. I pushed him off and ran even breaking my calculator in the process. This haunts me everyday and is one of the supsected reasons I know have a personality disorder. I don’t know how to move on ?
