Yeah, that's a good start. But you need to separate yourself not only physically from the person, but also mentally. Just stop thinking about him! Get him out of your head! Move on with your life. By now, you've probably created a mental picture of him which is so idealized that it doesn't reflect them in the slightest (especially if you did not know his personality to begin with).

Getting yourself out, making new connections is elementary to getting over the past. Your fear is keeping the issue alive. Is it going to be easy or fun at first? Probably not, but you have to try
