Nine months isn't really that long. It took me years to actually cut my ex out of my life and move on. I hate to tell you, but it took me about 5 years until I felt 'nothing' and some people never even make it to the point where they feel nothing. You met someone who shared a portion of your life and made an emotional impact....some people are better at shutting that off than others.
No contact is key, and like the above post said stay BUSY. Hang out with friends and family, fill your life with great people that make you forget.
