I went through the same thing with a girl who I didn't even have a real relationship with; the thinking about her everyday thing. I think it's a form of psychosis where you're still attached to a dream of "what may have been" or this is filling an emotional hole in your life.

My best advice is that it fades with time (about a year for me) but you really do have to work at it. This is a form of self-torture that you control, if that makes sense. Admit that it's a problem and this isn't good for you, then keep cutting him out of your life (and mind) until it's not something you need to do anymore.

I'd suggest you not talk to anyone about this (other than professional help of course). Not only does it get very boring for other people but a "sympathic ear" will actually keep old wounds fresh. One of my tricks was to write letters to myself and then burn them. I got my feelings out and then disposed of them sort of, without anyone getting hurt or (more important) getting myself embarrassed all over again.

*sidenote - I'm sure glad it never worked out with that girl. She was a total mess!
