I think your anger, instability, and obsessive behavior are enough to send alarm bells to anyone. Even if he liked you initially, or was in the process of getting to know you to see if he liked you, as soon as you start with the anger, the blame, the swearing, and the obsession-- you're likely to turn anyone off and send them running. That kind of behavior shows that you do not have control over your emotions and behavior and that's scary to most people. I think you need to deal with those issues in therapy before you seek a relationship. It's nearly impossible to have a healthy relationship until you are a healthy person.
