6months ago my girlfriend dumped me and cut me. I texted her, tried to ring her she got annoyed and just won't speak up. 3 months later I apologized which she acknowledged, so we walked our own ways and she admitted the way she did things was wrong. But cutting off leaves huge scars. 2 days ago I lost my shit and texted her telling her she is heartless and other stuff. She's going to college this year to another country and I just keep thinking about how I'm thought of the crazy ex amongst her and her friends. She didn't even reply to my insults, she blocked me and told her best friend that it was mean. How do I change the fact that she thinks I'm crazy. I know I may be but I want her to miss me. She's almost a neighbor so that's a problem too.
