I know how you feel.i broke up with this boy and we dated just four months and I still care for him and I can imagine you..2 years....!All I can say is that you have to find something that will occupy your thoughts, go out with friends, go to clubs, you'll find another guy that will replace the old one.One thing that always works for me is that I always think how he has moved on so it gives me a reason more not to think about him.You should move on to, life goes on without him )))
