Since the relationship ended 3 yrs. ago and you have had no contact with him, you can’t expect too much. The only way you will know for sure is if you contact him. If you are shy about talking to him, then perhaps a note would work better. You could let him know that you have moved to the area. If he responds and would like to see you, then you could take it from there.
However, if he doesn’t respond then it would be better to just let it go. I sense that there is someone else who you will meet that will be a better friend. In time you will realize that this is a blessing in disguise.
Take care!
