He broke up with me

It hurt so bad. He left with no clear reason. He just told me that he love me but he doesn't think he can do it anymore. He said his past will always going to haunt him and he don't want me to be involved in it. It doesn't make any sense. I tried to go to his house and i know it was stupid to do but i wanted to clear things up. I wasn't going to beg for him, i want to break up in a mature way. We're not highschool to just break up with me by texting me. I said yes in person when he asked me to be his girl, so i just wanted the same respect. So i was outside of his house but he didn't show up, telling me he's with his folks. He even threathen me that he will call cops if i don't leave (i was just standing there, i wasn't harrassing anybody) simply waiting for him. He even called me a psycho. I can't believe after everything we've been through, he didn't respect me in the end. I was so hurt and mad with myself for being stupid and to him.
