How does one move on?

[1 confused chic]

I am having a lot of trouble moving on. My ex has, or atleast he is pretty good at acting like it. He was my first love and I want to move on, but how? We were together for 7 mths and then it ended, but on the note that we were supposed to get back together. I now realize that I am stupid to think that it would happen, so what do I do. Is there anyway that I can get over him? Please help me.
