What are the positive signa you are getting over someone?

I've come a long, most people who haven't been in love won't get it, it's very difficult to get over someone. It's very painful, some say just forget about him and get mad about you reminesin or talking about him. But it takes time and patience... I'm happy just moments ago I was thinking of myself and how I can better my own life, wow it's strange new concept that I openly welcome. Because before I would just think of him and wallow in self pity. I tortured myself and I asked what could I have done to change him, so he can show me the love and effection I wanted. So it feels good now that I can focus on finding the same in myself.
