I have a ex guy friend who was sending me unwanted messages. I told him to stop texting me and to leave me a lone. He texted me three times and called me once after telling him to leave me alone. I talked to the police and they did a report and can't do anything else because he isn't threatening me. I told the police I don't feel safe due to his past history and him owning guns, and him knowing where I live, drive and my work schedule. I blocked his number. Is there anything else I can do.
