Get in a new relationship, When you miss him try to remember the worst part of him, keep yourself busy. But If you miss a lot and if you still think you might give him a chance text him and talk ( this is what i do lol but its not what i would recommend. If you moved on you should consider him past be with someone who worth it)

I was in the same situation many times and from experience I can say you can't really completely forget such a connection that has that type of impact and you will probably always remember it and look back on it. Whether you see him again sometimes soon or not, you most likely will not forget him. What will happen is that time will lessen the intensity. As time goes on, if you never see him again, you will stay on those constant thoughts and then eventually you will find that you still have that fondness for him, but it is not so constant. I felt similar to you about someone that was special to me. We lost complete touch and I missed him for years and couldn't stop thinking about him. I didn't think it would stop. Five years later the intensity stop, but I still think about him. With time and especially once you meet someone else it will lessen and probably for you it may completely go away. You cannot really control the thoughts so just let them be. They will slowly die out over time.
