Maybe you will get more joy, meeting up with him once in a while. I think you relied on this relationship for too long, and that's how you have become unhappy. Don't rely on people to make you happy, that's your responsibility.
The other reason you are unhappy you were relying on this relationship to make you happy, now that's gone, You don't know what to do with yourself, your like a lost child without its favorite toy. How about finding another toy to play with it? Now a very happy child would find another toy to play with. That child is independent.
